Memory Exhausted Error

Quick Fix

Increase PHP memory limit, disable heavy plugins, clear cache, restart server.

What it Means

The Memory Exhausted Error in WordPress means PHP ran out of allocated memory while executing a request. It stops the page load and shows an error to the user.

Possible Causes

• 1
  PHP memory_limit reached
• 2
  Large or poorly coded plugins/themes
• 3
  High traffic spikes
• 4
  Insufficient server RAM
• 5
  Memory leaks in custom code

Step-by-Step Solutions

1. Edit wp-config.php

   Add or modify the line define('WP_MEMORY_LIMIT','256M'); to give WordPress more memory.

2. Change php.ini

   Locate php.ini and set memory_limit = 256M; then restart the web server to apply changes.

3. Disable heavy plugins

   Go to the Plugins page, deactivate plugins that consume a lot of memory or replace them with lighter alternatives.

4. Clear cache

   Use WP-CLI or a caching plugin to flush all cached data, freeing memory.

   wp cache flush
5. Check memory usage

   Run a quick memory check to see peak usage and identify leaks.

   wp eval 'echo memory_get_peak_usage();'
