WordPress ‘Insufficient Memory Limit’ Error

If you receive the following error, you may need to increase your WordPress memory limit from a plugin or theme:

WP memory limit 40 MB Insufficient memory. You need at least 256MB of memory

One way to resolve this issue is to add the following line (which increases the memory limit) to the top of the ‘wp-config.php’ file.

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