Understanding WordPress Fatal Error
Defining WordPress Fatal Error
A WordPress fatal error is a critical issue that occurs when the code of a WordPress website encounters an unrecoverable error. This error not only causes the website to malfunction but also prevents any further execution of code, leading to a complete breakdown of the site. When a fatal error occurs, users are usually greeted with a message stating “Fatal error: Allowed memory size exhausted” or “Parse error: syntax error, unexpected”. It is important to understand the different types of fatal errors to effectively troubleshoot and fix them.
Common Causes of WordPress Fatal Error
There are several common causes that can trigger a fatal error in WordPress. One of the most common causes is a syntax error in the code. This can occur when there are typos, missing or misplaced brackets, or incorrect function names in the code. Another common cause is a memory exhausted error, which happens when the PHP memory limit is reached. Additionally, conflicts between plugins or themes, outdated software versions, and incompatible PHP versions can also contribute to fatal errors.
Impacts of WordPress Fatal Error
A WordPress fatal error can have significant impacts on your website. It not only disrupts user experience but also affects the reputation of your brand or business. When your website encounters a fatal error, it becomes inaccessible to visitors, leading to a loss in traffic, potential customers, and revenue. Moreover, if your website serves a critical function such as an e-commerce platform or a news site, a fatal error can completely disrupt your business operations. Therefore, it is crucial to address and fix these fatal errors promptly to ensure the uninterrupted functionality of your WordPress site.
Enable Debug Mode in WordPress
What is Debug Mode?
Debug mode in WordPress is a useful tool that helps developers and website owners identify and resolve errors more efficiently. When enabled, debug mode provides detailed error messages, warnings, and notices that can assist in pinpointing the exact cause of the issue. By default, debug mode is turned off in WordPress to prevent visitors from seeing potentially sensitive information. However, enabling it temporarily can greatly assist in troubleshooting and fixing fatal errors.
Steps to Enable Debug Mode
Enabling debug mode in WordPress involves a few simple steps. First, access your website’s root directory via FTP or the file manager provided by your hosting provider. Find the wp-config.php file and open it using a text editor. Look for the line that says define( 'WP_DEBUG', false ); and change it to define( 'WP_DEBUG', true );. Save the changes and upload the modified wp-config.php file back to your server. Once this is done, debug mode will be enabled, and any errors or warnings will be displayed on your website.
Reading Debug Logs
After enabling debug mode, it is important to monitor the debug logs to identify the specific error causing the fatal error. The debug logs can be found in the wp-content directory of your WordPress installation. Look for a file called debug.log and open it using a text editor. The log file will contain a timestamped record of all the errors, warnings, and notices encountered by your website. Carefully review the log file to find the relevant error message and note down the details for further troubleshooting.
Fix Syntax Error in WordPress
Understanding Syntax Error
A syntax error in WordPress refers to an error in the code that violates the rules of the programming language used. This can be caused by incorrect use of brackets, missing or misused quotation marks, or typographical errors in function names or variables. When a syntax error occurs, it prevents the code from executing correctly and triggers a fatal error. Identifying and correcting syntax errors is crucial to ensure the proper functioning of your WordPress website.
Identifying Line and File Causing Error
To identify the line and file causing a syntax error, it is advisable to review the error message displayed. WordPress usually provides detailed information about the error, including the file name and the line number where the error occurred. These details can help you pinpoint the exact location of the error within your code. Once you have identified the line and file causing the error, you can proceed to correct the syntax.
Correcting Syntax
Correcting syntax errors in WordPress involves carefully reviewing the code and fixing the mistakes. Start by focusing on the specific line mentioned in the error message. Check for any missing or misplaced brackets, incorrect function calls, or typographical errors in variable names. Once you have identified the mistake, make the necessary corrections. Remember to save the changes and upload the updated code to your server. After fixing the syntax error, test your website to ensure that the fatal error has been resolved.
Resolve WordPress Memory Exhausted Error
Reasons for Exhausted Memory
A memory exhausted error occurs in WordPress when the amount of memory allocated for PHP execution is insufficient to handle the demands of your website. This can happen due to several reasons, such as large image sizes, resource-intensive plugins or themes, inefficient code, or inadequate PHP memory limit settings. When the memory limit is reached, it triggers a fatal error and renders your website inaccessible.
Increasing PHP Memory Limit in WordPress
To resolve a memory exhausted error in WordPress, you need to increase the PHP memory limit. This can be done by editing the wp-config.php file in your website’s root directory. Open the file using a text editor and look for the line define( 'WP_MEMORY_LIMIT', '64M' );. Increase the memory limit value, such as 128M or 256M, depending on the requirements of your website. Save the changes and upload the modified wp-config.php file back to the server. This will allocate more memory to PHP execution and help prevent memory exhausted errors.
Alternative Methods to Increase Memory
If increasing the PHP memory limit through the wp-config.php file does not resolve the memory exhausted error, there are alternative methods to consider. One such method is editing the .htaccess file. Access the file using an FTP client or the file manager provided by your hosting provider and add the following line of code at the beginning of the file: php_value memory_limit 256M. Save the changes and test your website to see if the error is resolved. Another option is to contact your hosting provider and request an increase in the PHP memory limit. They may be able to assist you in adjusting this setting.

Addressing Error Establishing Database Connection
Why Database Connection Errors Occur
An error establishing a database connection in WordPress can occur due to multiple reasons. One common cause is incorrect database credentials. If the username, password, database name, or host details specified in the WordPress configuration file (wp-config.php) are incorrect, the connection to the database cannot be established, resulting in a fatal error. Other potential causes include database corruption, server overload, or issues with the database server.
Checking Database Login Credentials
To address an error establishing a database connection, the first step is to verify the database login credentials. Open the wp-config.php file in your website’s root directory and locate the lines that define the database name, username, password, and host. Verify that the information provided is correct and matches the configuration details of your database. If any information is incorrect, make the necessary corrections and save the changes. Test your website to see if the error is resolved.
Repairing Corrupted Database
If the database login credentials are correct and the error persists, it is possible that the database itself is corrupted. In such cases, you can repair the database using the inbuilt database repair functionality provided by WordPress. To initiate the repair process, add the following line of code to the wp-config.php file, just above the line that says /* That's all, stop editing! Happy blogging. */: define( 'WP_ALLOW_REPAIR', true );. Save the changes and access the repair page by visiting http://www.yourwebsite.com/wp-admin/maint/repair.php. Follow the on-screen instructions to repair your database.
Fix the Internal Server Error in WordPress
Determining Causes of Internal Server Error
An internal server error in WordPress can be frustrating as it provides limited information about the underlying cause. However, there are common causes to consider when troubleshooting this error. One possible cause is a corrupted .htaccess file. Another cause can be conflicts between plugins or themes. Additionally, insufficient file permissions, memory allocation issues, or outdated software versions could also contribute to internal server errors.
Checking for Corruption in .htaccess File
To check for corruption in the .htaccess file, access your website’s root directory using an FTP client or the file manager provided by your hosting provider. Locate the .htaccess file and rename it to something like .htaccess_backup. This will effectively disable the file. Reload your website to see if the internal server error is resolved. If it is, it means the issue was caused by a corrupted .htaccess file. To fix this, go to the WordPress admin dashboard, navigate to Settings > Permalinks, and click the “Save Changes” button. This will generate a new .htaccess file with the correct configurations.
Deactivating Plugins and Themes
If disabling the .htaccess file does not resolve the internal server error, it is worth exploring conflicts with plugins or themes. Temporarily deactivate all plugins by renaming the plugins folder in the wp-content directory to something like plugins_backup. Refresh your website to check if the error is resolved. If it is, reactivate the plugins one by one, testing your website after each activation, to identify the problematic plugin. Similarly, if you suspect a theme conflict, switch to a default WordPress theme and see if the error persists. Once the problematic plugin or theme is identified, consider updating, reinstalling, or finding an alternative to resolve the error.
