 * Hi there –
 * I’m getting the PHP out of memory error, but only for non-admin users:
 * Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate
   75 bytes) in /***/htdocs/wordpress/wp-content/plugins/w3-total-cache/lib/W3/Plugin/
   TotalCacheAdmin.php on line 5682
 * I don’t have access to the php.ini file at this hosting provider, so I’ve tried
   increasing the PHP memory from 32M to 64M in the wp-config file and in the .htaccess
   file, but neither option is making a difference.
 * Everything works fine as long as I’m logged in as the admin user, but I wanted
   to create an account with editor level access for my client.
 * Any suggestions?
 * Thanks in advance for any help!!!

 * I finally found a solution that works …
 * Add these two lines to wp-settings.php:
 * define(‘WP_MEMORY_LIMIT’, ’64M’);
    ini_set(“memory_limit”, “64M”);
 * I’m not sure why I was still having trouble after increasing the PHP memory limit
   using the wp-config.php file or the .htaccess file, but this one worked.
