How to increase the PHP memory limit in WordPress Print

If you see "Allowed memory size exhausted", WordPress needs more PHP memory.

Step 1: Raise PHP's limit

1. In cPanel, open MultiPHP INI Editor in the Software section.
2. Choose your domain.
3. Set memory_limit to 256M (or 512M for heavy sites) and click Apply.

Step 2: Tell WordPress

Edit wp-config.php and add this line above /* That's all, stop editing! */:

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

Check it worked

Go to Tools › Site Health › Info › Server and look at the PHP memory limit.

Note: your hosting account also has an overall memory limit (see How to understand resource limits). If a site needs more than that, find out which plugin is using so much memory or consider a larger package.
