Overcoming the Wordpress “Fatal Error: Allowed Memory Size” Error
By Chad A. Johnson · June 3, 2009
If you are like me, you love Wordpress for it’s extendability. Through the use of plugins, new features and functionality can be easily added. Because of this, Wordpress is one of the best platforms to build a real estate agent website on.
While plugins can be a blessing, they also can cause problems with a website. This can come in the way of slow website performance or error messages.
One common error message experienced by those getting a bit “plugin happy” (activating a lot of plugins on a single Wordpress installation) is that of the “Fatal Error: Allowed memory size…” error.
This error message is a result of Wordpress exceeding it’s predetermined memory limit. Activating several large, high-functionality plugins can easily cause this problem.
Luckily, there is an easy fix.
Wordpress sets its memory limits within the wp-settings.php file. All that has to be done is change the memory limit from “32M” to “64M”.
Here are the step by step instructions:
- Open wp-settings.php in your favorite code editor. This file is in the root directory of your Wordpress installation
- Go to line #13 of wp-settings.php and locate ‘32M’
- Change the “32″ to “64″
- Save the file and FTP it to your server
Once this is complete, you should have no problems activating those large plugins. Keep in mind that too many plugins can negatively affect website performance, so choose your plugins wisely and only add those that add value to the visitor experience.

Tried auto-upgrade from 2.8.6 to 3.0 and got the memory error message.
Typed first half of error message into Google and got your site.
Tried your fix and the upgrade went smoothly.
Thanks very much for posting this really helpful tip.
I have had this happen on one of my sites which has been upgraded to v3.0 but unfortunately it does not give the option to change WP MEMORY LIMIT in wp-settings.php
Is there another way?
Thanks in advance
