Increasing the WordPress Memory Limit

To address memory limit issues, there are two paths:

• Adjust yourself
• Contact your hosting company

To adjust on your own, here are some methods to try. Be aware that this section requires advanced knowledge; it is not basic.

Add this to the top, before the line that says, “Happy Blogging”:

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

http://codex.wordpress.org/Editing_wp-config.php#Increasing_memory_allocated_to_PHP

If you have access to your PHP.ini file, change the line in PHP.ini
If your line shows 64M try 256M:

memory_limit = 256M ; Maximum amount of memory a script may consume (64MB)

If you don’t have access to PHP.ini try adding this to an .htaccess file:

php_value memory_limit 256M

Should you not feel comfortable in trying the above methods, or the above did not work for you, you need to talk to your hosting about having them increase your memory limit.
