Increasing PHP Memory Limit

In some cases, hosts will set a limit on the amount of memory WordPress can use, and this can cause certain issues, like the Customizer not being able to save or even load (just shows a white screen).

There’s a couple different ways to increase your memory limit.

Easiest Method

Just ask your host – they’ll more than likely be happy to increase your memory limit.

Edit wp-config.php

The WordPress Codex has an article on this here.

Find your wp-config.php file in the root of your WordPress installation by using FTP.

Then add this to it:

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