Fix the WordPress Memory Exhausted Error – Increase PHP Memory

Fix the WordPress Memory Exhausted Error – Increase PHP Memory

Are you seeing a “Fatal error: Allowed memory size of X bytes exhausted” on your WordPress site? This memory exhausted error is common and typically means your website is hitting the PHP memory limit set by your hosting environment.

Thankfully, increasing the PHP memory limit in cPanel is simple and can quickly resolve this issue.

What Causes the Memory Exhausted Error in WordPress?

- High-resource plugins or themes
- Large file uploads or media processing
- Poorly coded custom functions or loops
- Too many active plugins consuming memory

Step-by-Step: How to Fix It by Increasing PHP Memory

1. Modify the wp-config.php File

The quickest way to raise the memory limit is through wp-config.php.

- Log in to cPanel
- Go to File Manager > public_html
- Locate wp-config.php and click Edit
- Add the following line just before the line that says "That's all, stop editing":

define('WP_MEMORY_LIMIT', '256M');

- Save the file and reload your site

2. Increase Memory in .htaccess File (If Allowed)

If you can’t modify wp-config.php or need to enforce the limit:

- In File Manager, locate the .htaccess file in public_html
- Add this line:

php_value memory_limit 256M

- Save and check your site again

Note: This may trigger a 500 error on some shared hosts if not supported.

3. Use MultiPHP INI Editor in cPanel

If your host uses MultiPHP:

- Go to cPanel > Software > MultiPHP INI Editor
- Select your domain from the dropdown
- Find memory_limit and change the value to 256M (or higher if needed)
- Click Apply

4. Update php.ini or .user.ini File

If you have access to php.ini or user.ini (depends on hosting):

- Go to File Manager > public_html
- Create or edit php.ini or .user.ini
- Add this line:

memory_limit = 256M

- Save and test your website

5. Contact Hosting Support

If none of the above work, your hosting provider may have hard limits in place. Contact support and ask them to raise your PHP memory limit.

Final Thoughts

Running into a memory exhausted error is frustrating, but it’s one of the easiest WordPress issues to resolve. A small increase in PHP memory often fixes performance problems and crashes instantly.
