Understanding the WordPress White Screen of Death
The WordPress White Screen of Death is a frustrating issue that many WordPress users have encountered at least once. It refers to a condition where the entire website or admin page appears completely blank, displaying only a white screen. This issue is particularly problematic because it prevents you from accessing and managing your website effectively. In this article, we will explore the common causes of the WordPress White Screen of Death and provide comprehensive troubleshooting steps to help you resolve it.
What is WordPress White Screen of Death?
The WordPress White Screen of Death occurs when there is a critical error in your WordPress installation that prevents the website or admin area from loading properly.

Common Causes Triggering the WordPress White Screen of Death
There are several common causes that can trigger the WordPress White Screen of Death. These include:
- Plugin or theme conflicts: Incompatible or poorly coded plugins and themes can conflict with each other or the WordPress core, leading to the white screen issue.
- Insufficient memory limit: If your website’s PHP memory limit is too low, it can hinder the proper functioning of your website and result in the white screen problem.
- Syntax errors: Errors in code syntax, such as missing or misplaced characters, can cause the white screen to appear.
- Cache and cookie issues: Accumulated cache files or faulty cookies can disrupt the loading process and lead to the white screen.
- CDN conflicts: Content Delivery Networks (CDNs) can sometimes conflict with WordPress, causing the white screen issue.
- Server-related problems: Issues with server configuration, updates, or compatibility can also trigger the white screen.
Now that we have a basic understanding of the WordPress White Screen of Death and its common causes, let’s delve into the troubleshooting steps to resolve this frustrating issue.
Initial Checks Before Troubleshooting
Before diving into complex troubleshooting steps, it’s important to perform some initial checks to narrow down the potential causes of the White Screen of Death. Here are the initial checks you should carry out:
Checking if the admin section is working
To determine if the issue is specific to your website’s frontend or if it affects the entire WordPress installation, try accessing the admin section of your website. If the admin section is accessible and functioning properly, it indicates that the problem is likely related to a theme or plugin conflict affecting your website’s frontend.
Verifying if the issue is occurring in all browsers
Sometimes, the White Screen of Death may occur only in a specific browser due to compatibility issues. To rule out browser-related problems, try accessing your website using different browsers like Chrome, Firefox, or Safari. If the issue persists across all browsers, it suggests that the problem lies within your WordPress installation.
Inspecting the website on a different device
If possible, try accessing your website using another device such as a smartphone or tablet. This will help determine if the White Screen of Death is device-specific or if it extends across multiple devices. If the issue persists on different devices, it suggests that the problem is related to your website rather than the device itself.
By performing these initial checks, you can gain valuable insights into the nature and scope of the White Screen of Death issue, which will assist you in troubleshooting and finding an appropriate solution.

Increasing Memory Limit
Insufficient PHP memory limit is a common cause of the WordPress White Screen of Death. The PHP memory limit determines the maximum amount of memory that can be allocated to PHP processes on your server. When this limit is exceeded, it can lead to various errors, including the white screen issue. Here’s how you can increase your PHP memory limit:
Understanding how PHP memory limit affects your website
The PHP memory limit directly affects the performance and functionality of your WordPress website. When the PHP memory limit is too low, it restricts the execution of certain processes, causing conflicts and errors, including the White Screen of Death. By increasing the memory limit, you allow your website to utilize more resources, potentially resolving the issue.
Steps to increase PHP memory limit
To increase the PHP memory limit, you can make changes to the wp-config.php file or the .htaccess file, depending on your server configuration. Here’s how:
-
Modifying the
wp-config.phpfile: Access the root directory of your WordPress installation and locate thewp-config.phpfile. Open it in a text editor and add the following line of code just before the line that says/* That's all, stop editing! Happy blogging. */:define('WP_MEMORY_LIMIT', '256M');. Save the changes and refresh your website to see if the White Screen of Death issue has been resolved. -
Modifying the
.htaccessfile: If you don’t have access to thewp-config.phpfile or prefer to make changes in the.htaccessfile, you can try this alternative method. Locate the.htaccessfile in the root directory of your WordPress installation and add the following code at the bottom:php_value memory_limit 256M. Save the file and check if the White Screen of Death issue has been resolved.
Troubleshooting issues when increasing memory limit
Sometimes, increasing the PHP memory limit may not immediately resolve the White Screen of Death issue. If that’s the case, here are some additional troubleshooting steps you can take:
-
Plugin conflict: Disable all plugins temporarily and check if the white screen persists. If it resolves the issue, gradually enable each plugin until the culprit is identified.
-
Theme conflict: Temporarily switch to a default WordPress theme like Twenty Twenty-One to see if the white screen issue disappears. If it does, it indicates a compatibility issue with your previous theme.
-
Server limitations: In some cases, your hosting provider might have imposed restrictions on increasing the PHP memory limit. Contact your hosting support to ensure you are allowed to make such modifications.
By following these steps, you should be able to increase your PHP memory limit effectively and resolve any related issues causing the WordPress White Screen of Death.
Deactivating Themes and Plugins
One of the most effective troubleshooting methods for the WordPress White Screen of Death is deactivating themes and plugins. Conflicts between themes and plugins can often lead to the white screen issue. Here’s how you can go about it:
Why deactivating themes and plugins?
Themes and plugins add functionality and styling to your WordPress website. However, conflicts can arise between them, causing errors and the white screen problem. By deactivating themes and plugins, you can identify and resolve any conflicts that may be causing the issue.

- Locate the plugin you wish to deactivate and click on the “Deactivate” link below it.
- Refresh your website to check if the white screen issue has been resolved.
Identifying problematic themes and plugins
After deactivating themes and plugins, you need to identify the ones causing conflicts. To do this, reactivate each theme and plugin one by one, and refresh your website after each activation. If the white screen issue reappears after activating a specific theme or plugin, it suggests that it is the root cause of the problem. Consider finding an alternative or seeking support from the theme or plugin developer to resolve the conflict.
By following the process of deactivating themes and plugins, you can effectively identify and resolve conflicts that may be triggering the WordPress White Screen of Death.

Syntax errors are code errors that occur when the code structure violates the programming language’s rules. They can range from missing or misplaced characters to incorrect syntax usage, causing the entire code to fail and resulting in the white screen issue.
How to detect syntax errors?
To detect and locate syntax errors, follow these steps:
- Access your WordPress installation’s file directory using an FTP client or the File Manager provided by your hosting provider.
- Locate the file causing the issue. Common files to check are
functions.phpwithin the active theme directory or any custom code files you may have added. - Open the file in a text editor and carefully review the code for any syntax errors. Look for missing parentheses, semicolons, or any other code elements that may cause a syntax error.
Correcting syntax errors
If you find any syntax errors, correct them by fixing the code according to the language’s syntax rules. Once you have made the necessary changes, save the file and refresh your website to see if the white screen issue has been resolved.
By carefully reviewing your code and correcting any syntax errors, you can eliminate one of the potential causes of the WordPress White Screen of Death.

Deleting cookies related to the website
To delete cookies related to your website, follow these general steps:
- Access your browser’s settings.
- Look for the “Privacy” or “Cookies” section.
- Find the option to manage cookies or delete specific cookies.
- Search for cookies related to your website and delete them.
- Close and reopen your browser before accessing your website again.
By clearing the cache and deleting cookies, you can eliminate any potential conflicts caused by outdated or corrupted files and cookies, potentially resolving the WordPress White Screen of Death issue.
Disabling CDN Temporarily
Content Delivery Networks (CDNs) are commonly used to improve website performance and user experience. However, in some cases, CDNs can conflict with WordPress, causing the white screen issue. Here’s how you can temporarily disable your CDN:
Understanding the CDN and its role
A CDN is a distributed network of servers that deliver website content to users based on their geographic location, reducing page load times and improving website performance. CDNs cache and serve static content like images, stylesheets, and scripts, enhancing the overall user experience.
Why disable CDN?
Sometimes, CDNs can interfere with the functioning of WordPress, causing conflicts that result in the white screen issue. By temporarily disabling the CDN, you can determine if it is the root cause of the problem. If the white screen disappears after disabling the CDN, it suggests that there is a compatibility issue between the CDN and your WordPress installation.
How to temporarily disable CDN?
Disabling the CDN depends on the specific service you are using. Here are some general steps to follow:
- Log in to your CDN provider’s website.
- Access the settings or configuration options for your website.
- Look for an option to temporarily disable the CDN or put it into “development mode.”
- Save the changes and wait for the changes to propagate, as it may take some time.
- Refresh your website to see if the white screen issue is resolved.
Temporarily disabling the CDN will help you identify if it is the cause of the WordPress White Screen of Death. If it is indeed the cause, you may need to reach out to your CDN provider for further assistance or consider switching to a different CDN service.

Switching to Default WordPress Theme
If you suspect that the issue is related to your current theme, switching to the default WordPress theme can help identify if the theme is causing the white screen issue. Here’s how you can do it:
Why switch to default WordPress theme?
Default WordPress themes, such as Twenty Twenty-One, are well-optimized and regularly updated by the WordPress team. By switching to the default theme, you can determine if the white screen issue is caused by a compatibility problem or code conflict within your current theme.
Steps to switch to default WordPress theme
To switch to the default WordPress theme, follow these steps:
- Access your WordPress admin dashboard and navigate to the “Appearance” menu.
- Click on “Themes” to view all the installed themes.
- Locate the default WordPress theme, such as Twenty Twenty-One.
- Hover over the default theme and click the “Activate” button.
- Refresh your website to check if the white screen issue has been resolved.
By switching to the default WordPress theme, you can determine if the issue lies within your current theme. If the white screen disappears with the default theme, it suggests that there is a compatibility issue or conflict with your previous theme.
Finding the issue with your theme
If switching to the default WordPress theme resolves the white screen issue, it indicates that there is a problem with your previous theme. Consider reaching out to the theme developer or community for assistance in resolving the compatibility issue or consider choosing an alternative theme that meets your requirements.
