One of the drawbacks of using WordPress 3.0 is the memory limitation. Although easily changed as described below, it  had good intentions.

The primary reasoning for WordPress’ built in memory limit was to save your websites’ memory being consumed by poorly written plugins.

WordPress’ standard memory limit is set to 32MB but by going into your wp-config.php file and adding the following line of code, you should have no more problems:

define(‘WP_MEMORY_LIMIT’, ’96M’);

Of course, another way to just avoid this is issue is to upgrade your WordPress from 3.0 to the latest version! Starting with WordPress 3.2, the memory limit is configurable again and won’t be an issue.
