Fatal Error Exhausted Memory Size When Upgrading to WordPress 3.0? Here’s the Fix.

This is a common problem among WordPress users upgrading to 3.0 since the package size is bigger than previous versions. You may see something like this:

Fatal error: Allowed memory size of 33554432 bytes exhausted

Solution: Increase Memory Limit:

One way to do this is to add this line to your wp-config.php file:

define('WP_MEMORY_LIMIT', '64M');

Another solution that some may be more comfortable with is to install a plugin to help you increase the memory limit. Check out Memory Limit. You can install and activate it for your upgrade. Then you can deactivate it afterwards if you want to.
