Finding the Cause of the Fatal Error
When you encounter a fatal error on your WordPress website, it can be quite alarming. However, before you panic, there are several steps you can take to determine the cause of the error. These steps will help you pinpoint the issue and find the best solution to fix it.
Checking the Error Message
The first thing you should do when faced with a fatal error is to carefully read and analyze the error message. The error message usually provides valuable information that can help you understand what went wrong. Look for any specific error codes or error descriptions that can give you a clue about the cause of the problem.
Reviewing Recent Changes or Updates
Another important step in finding the cause of a fatal error is to review any recent changes or updates made to your WordPress website. Whether it’s a new plugin, theme, or WordPress core update, any recent changes can potentially trigger conflicts or compatibility issues leading to the fatal error. By identifying these recent changes, you can focus your troubleshooting efforts on the areas that are most likely to be the cause.
Analyzing the Error Logs
Error logs are an invaluable resource when it comes to troubleshooting fatal errors. WordPress generates error logs that can provide detailed information about what happened leading up to the error. These logs usually contain timestamps, error types, and related error messages. Analyzing the error logs can help you identify the sequence of events that led to the fatal error and narrow down the possible causes.
Fixing the Fatal Error
Once you have identified the cause of the fatal error, it’s time to take action and fix the issue. Here are several methods you can try to resolve the problem and get your WordPress website back up and running smoothly.
Deactivating Plugins
Plugins are a common source of conflicts and fatal errors in WordPress. If you suspect that a plugin is causing the issue, you can try deactivating all your plugins simultaneously. This can be done by accessing your WordPress dashboard, navigating to the “Plugins” section, and selecting “Deactivate” for all plugins. By doing this, you can determine if any of the plugins were indeed causing the fatal error.
Changing the Theme
Similar to plugins, themes can also be responsible for fatal errors. If you recently changed or updated your WordPress theme, it’s worth considering reverting to a default WordPress theme such as Twenty Twenty-One. Changing the theme will help you determine if the fatal error is theme-related or caused by something else.
Updating WordPress
Keeping your WordPress installation up to date is crucial for both security and compatibility. If you haven’t already, try updating your WordPress core files to the latest version. WordPress updates often include bug fixes and enhancements that can help address fatal errors caused by outdated software.
Increasing PHP Memory Limit
Sometimes, a fatal error can occur due to insufficient memory allocated to PHP. By increasing the PHP memory limit, you provide more resources for your WordPress website to run smoothly. To do this, you can edit the php.ini file or modify the .htaccess file. Alternatively, you can also edit the wp-config.php file to increase the PHP memory limit.
Repairing Corrupted Files
Corrupted files can also lead to fatal errors in WordPress. To repair these files, you can utilize WordPress’s built-in file recovery feature. This feature automatically checks and repairs corrupted files, helping to resolve any fatal error caused by file corruption. Additionally, you can manually reinstall critical WordPress files to ensure all the necessary files are intact and functioning properly.
Reinstalling WordPress Core Files
If the fatal error persists even after attempting the above methods, you may need to reinstall the entire WordPress core files. This process replaces all the core files with fresh copies, eliminating any potential issues caused by corrupted or modified files. You can reinstall the WordPress core files either through the WordPress dashboard or via FTP.
Resolving Plugin-Related Fatal Errors
Plugins play a significant role in extending the functionality of your WordPress website. However, conflicts with plugins can also result in fatal errors. Here are some steps you can take to address plugin-related fatal errors.
Disabling Recently Installed Plugins
Start by disabling any recently installed plugins. If you recently added a new plugin and the fatal error occurred shortly after, there’s a high likelihood that the new plugin is causing the issue. By deactivating the recently installed plugins one by one, you can identify the specific plugin responsible for the fatal error.
Updating Incompatible Plugins
Plugins that haven’t been updated to match the latest version of WordPress can cause compatibility issues and fatal errors. If you suspect an incompatible plugin is causing the problem, check for plugin updates in the WordPress plugin repository or contact the plugin developer for information about compatibility with the current WordPress version. Updating the plugin to a compatible version can often resolve the fatal error.
Checking Plugin Compatibility with Current WordPress Version
Along with updating incompatible plugins, it’s important to ensure that all your plugins are compatible with the version of WordPress you are using. Some plugins may have specific minimum requirements or may not be actively maintained. By reviewing the plugin documentation or contacting the plugin developer, you can verify if the plugin is compatible with your WordPress version.
Reinstalling Plugins
If none of the above steps prove successful, you may need to reinstall the problematic plugin. This process involves deactivating and deleting the plugin, followed by reinstalling it from scratch. Reinstalling the plugin ensures that its files are fresh and properly installed, which can help eliminate any potential conflicts causing the fatal error.
Addressing Theme-Related Fatal Errors
Themes control the overall appearance and design of your WordPress website. However, theme-related conflicts or errors can also lead to fatal errors. Here are some steps to address theme-related fatal errors.
Switching to a Default WordPress Theme
If you suspect that your current theme is causing the fatal error, consider switching to a default WordPress theme such as Twenty Twenty-One. Default themes are well-tested, regularly updated, and generally more stable. By switching to a default theme, you can determine if the fatal error is specific to your current theme or caused by other factors.
Updating the Theme
Like plugins, themes need regular updates to ensure compatibility and security. If you are using a custom theme or a third-party theme, make sure you have installed the latest updates. Theme updates may include bug fixes and enhancements that can resolve fatal errors caused by outdated or incompatible themes.
Checking Theme Compatibility
If you recently updated your WordPress version or installed a new plugin, compatibility issues with your theme may arise. Check the theme documentation or contact the theme developer for information on compatibility with the current WordPress version and any installed plugins. Ensuring compatibility with your website’s components is crucial to preventing fatal errors.
Reinstalling the Theme
If the fatal error persists after updating and checking compatibility, consider reinstalling the theme. Reinstalling the theme involves removing the current theme and then reinstalling it from the original source or a fresh download. This process replaces any potentially corrupted or modified theme files, resolving any issues that may have caused the fatal error.

Updating WordPress to Fix Fatal Errors
Regularly updating WordPress is essential for security, performance, and compatibility. Here are two methods to update your WordPress installation.
Using the WordPress Dashboard
The easiest way to update WordPress is through the WordPress dashboard. When a new version is available, you will see a notification on your dashboard. Simply click on the “Please update now” link to initiate the update process. Follow the on-screen instructions to complete the update. Make sure to create a backup of your website before proceeding with the update to safeguard your data.
Updating Manually via FTP
If you prefer a manual approach or are unable to update through the dashboard, you can update WordPress manually using FTP (File Transfer Protocol). This process involves downloading the latest WordPress version from the official WordPress website, extracting the files, and replacing the existing WordPress files on your web server. Detailed instructions can be found on the official WordPress website to guide you through the manual update process.
Increasing PHP Memory Limit
PHP memory limit defines the maximum amount of memory PHP can allocate for its processes. When your website exceeds this limit, it can lead to fatal errors. Here are three methods to increase the PHP memory limit.
Editing php.ini
Locate the php.ini file on your web server. If you are unsure of its location, contact your hosting provider for assistance. Open the php.ini file with a text editor and search for the line that specifies the PHP memory_limit. Modify the value to increase the memory limit, save the changes, and restart your web server for the changes to take effect.
Editing .htaccess file
If you don’t have access to the php.ini file, you can try increasing the PHP memory limit through the .htaccess file. This file is located in the root folder of your WordPress installation. Open the .htaccess file and add the following line at the bottom:
php_value memory_limit 256M Save the file, and refresh your website to see if the fatal error is resolved. Note that not all hosting providers allow this method, so it’s important to check with your hosting provider or refer to their documentation before making any changes.
Editing wp-config.php file
If the previous methods do not work, you can also attempt to increase the PHP memory limit by editing the wp-config.php file. This file is located in the root folder of your WordPress installation. Open the wp-config.php file and add the following line before the “That’s all, stop editing!” comment:
define('WP_MEMORY_LIMIT', '256M'); Save the file, and refresh your website to see if the fatal error is resolved. Keep in mind that some hosting providers may restrict the PHP memory limit, so this method may not always be effective.

Repairing Corrupted Files
Corrupted files can trigger fatal errors on your WordPress website. Here are two methods to repair corrupted files.
Using WordPress Built-in File Recovery
WordPress has a built-in file recovery feature that can help repair corrupted files. To access this feature, log in to your WordPress dashboard, navigate to “Updates,” and click on the “Re-install Now” button next to the affected plugin, theme, or WordPress core file. WordPress will automatically download and replace the corrupted file with a fresh copy.
Reinstalling Critical WordPress Files
If the built-in file recovery feature does not resolve the fatal error, you may need to manually reinstall critical WordPress files. Download the latest version of WordPress from the official website, extract the files, and replace the corresponding files on your web server. This process ensures that all the necessary WordPress files are intact and can help fix any fatal errors caused by corrupted files.
Reinstalling WordPress Core Files
If none of the previous methods resolve the fatal error, you may need to reinstall the entire WordPress core files. Here are two methods to reinstall WordPress core files.
Using the WordPress Dashboard
Begin by creating a full backup of your WordPress website to protect your data. Then, log in to your WordPress dashboard, navigate to “Updates,” and click on the “Re-install Now” button next to the WordPress version number. WordPress will download and replace the core files, ensuring that any corrupted or missing files are restored.
Using FTP
If you are unable to access your WordPress dashboard, you can reinstall the WordPress core files manually using FTP. Follow the same procedure as updating WordPress manually via FTP, but instead of replacing specific files, replace all the existing WordPress files with a fresh copy from the downloaded WordPress version. This comprehensive reinstallation ensures that all the core files are properly installed and can help resolve stubborn fatal errors.

Disabling Recently Installed Themes
If you recently installed a new theme that caused a fatal error, here’s how you can disable it.
Accessing WordPress via FTP
Connect to your web server using an FTP client and navigate to the “wp-content” folder. Inside the “wp-content” folder, locate the “themes” folder and open it. Locate the folder of the recently installed theme, right-click on it, and select “Rename.” Add “old” or any other descriptive term to the folder name to disable the theme.
Renaming the Theme Folder
By renaming the theme folder, you essentially deactivate the theme without deleting it. This allows you to access your WordPress dashboard and troubleshoot the issue further without the problematic theme causing any fatal errors.
Fixing Fatal Errors Caused by Insufficient Server Resources
If your website is experiencing fatal errors due to insufficient server resources, here are some steps you can take to address the issue.
Contacting Your Hosting Provider
When you encounter fatal errors caused by insufficient server resources, one of the first steps you should take is to contact your hosting provider. Explain the issue and provide any relevant error messages or details you have gathered. Your hosting provider can assess your current hosting plan and provide guidance on whether you need to upgrade to a higher-tier plan.
Upgrading Your Hosting Plan
If your website consistently faces fatal errors due to resource limitations, upgrading your hosting plan may be necessary. A higher-tier plan typically offers more server resources such as CPU, memory, and storage, which can help alleviate the strain on your website and prevent fatal errors. Consult with your hosting provider to determine the best plan for your website’s needs.
Optimizing Your Website
In addition to upgrading your hosting plan, optimizing your website can also help reduce the strain on server resources. Consider implementing caching mechanisms, minimizing the number of plugins and themes, optimizing images, and using content delivery networks (CDNs) to improve performance and reduce the likelihood of fatal errors caused by insufficient server resources.
In conclusion, encountering a fatal error on your WordPress website can be stressful, but with a systematic approach, it can be resolved. Remember to thoroughly investigate the cause of the error, try different troubleshooting methods, and consult with professionals or support communities if needed. By following the steps outlined in this article, you’ll be well on your way to fixing fatal errors and ensuring the smooth operation of your WordPress website.
