WordPress Fatal Error Allowed Memory Size Exhausted Fix
What You Are Experiencing
Do any of these sound familiar?
Your WordPress site is down, displaying a blank page, or showing a cryptic error message about memory. This is a serious issue that prevents your site from loading, often indicating a deeper problem than a simple glitch. You're likely seeing a WordPress fatal error allowed memory size exhausted message, and your site is completely inaccessible.
If any of these match, you are in the right place. This is a specific type of WordPress critical error on website that requires immediate attention, sometimes related to other WordPress PHP fatal errors.
Root Cause
Why this happens
A WordPress fatal error allowed memory size exhausted occurs when a script on your website tries to use more memory than the server's PHP configuration allows. This limit is in place to prevent a single script from consuming all server resources, which could crash the entire server.
Common culprits include poorly coded plugins or themes, large image uploads, complex database queries, or a high volume of traffic. Sometimes, an update to WordPress core, a plugin, or a theme can introduce new memory demands, leading to this error. This is similar to a WordPress fatal error after plugin, theme or core update.
Essentially, your WordPress installation is asking for more RAM than it's been allocated. This isn't always a sign of a faulty server; often, it points to inefficient code or an undersized memory limit for your site's specific needs, resulting in a WordPress out of memory fatal error.
Try This First
Steps you can take right now
Work through these in order. Each step is safe unless noted otherwise.
Increase Memory Limit in wp-config.php
The most common and safest first step to address a WordPress allowed memory size of bytes exhausted fix is to increase the memory limit directly in your wp-config.php file. Access your site via FTP or your hosting control panel's file manager. Locate wp-config.php in the root directory of your WordPress installation. Add or modify the following line above the /* That's all, stop editing! Happy publishing. */ comment.
define( 'WP_MEMORY_LIMIT', '256M' );
Modify php.ini (If Accessible)
If editing wp-config.php doesn't resolve the WordPress out of memory fatal error, your server's PHP configuration might be overriding it. If you have access to your php.ini file (often found in your hosting account's root or public_html directory), locate the memory_limit directive and increase its value. Be cautious; incorrect edits here can cause other issues.
memory_limit = 256M
Adjust Memory Limit in .htaccess
Some hosting environments allow you to override PHP settings via the .htaccess file. This file is located in your WordPress root directory. Open it and add the following line. If you already have a php_value memory_limit directive, modify that instead. Always back up your .htaccess file before making changes, as errors can make your site inaccessible.
php_value memory_limit 256M
Identify the Culprit Plugin or Theme
If increasing the memory limit doesn't work, a specific plugin or theme is likely consuming excessive resources, leading to the WordPress memory limit fatal error fix. Access your site via FTP and rename the wp-content/plugins folder to something like plugins_old. This deactivates all plugins. If your site comes back online, reactivate plugins one by one to find the problematic one. Do the same for your theme by activating a default WordPress theme (e.g., Twenty Twenty-Four) by renaming your current theme folder in wp-content/themes.
