If you run Wordpress and ever receive a message such as “Allowed memory size of xxxxxx bytes exhausted” then you’re not alone. Resolving the error isn’t a big deal though. As of v2.5 the WP_MEMORY_LIMIT option allows you to specify the maximum amount of memory that can be consumed by PHP.

This wasn’t in my config already, but simply adding it fixed the issue.

This setting increases PHP Memory only for WordPress, not other applications.

Please note, this setting may not work if your host does not allow for increasing the PHP memory limit–in that event, contact your host to increase the PHP memory limit. Also, note that many hosts set the PHP limit at 8MB.

Increase PHP Memory to 64MB
define(’WP_MEMORY_LIMIT’, ‘64M’);
Increase PHP Memory to 96MB
define(’WP_MEMORY_LIMIT’, ‘96M’);
