# 500 Server Error – users.php

 * One of the users on my site was trying to update a bulk list of all users, and
   now the page will not load at all. I am getting a 500 Server Error, debug info
   shows the following:
 * > Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate
   > 72 bytes) in /wp-includes/wp-db.php on line 1548
 * I am unable to locate anything specific in that line of code, but have tried 
   suggestions to increase the memory including editing the .htaccess file, php.
   ini, and define(‘WP_MEMORY_LIMIT’, ‘1024M’);
 * None of these solutions have worked. I also tried finding a database table suggested
   here: [http://wordpress.org/support/topic/set-users-per-page-to-999-now-i-get-internal-server-error?replies=5](http://wordpress.org/support/topic/set-users-per-page-to-999-now-i-get-internal-server-error?replies=5)
   
   but I was unable to locate any meta key with users_per_page as suggested
 * Everything else on the site works fine, it is only the All Users page at wp-admin/
   users.php which throws the 500 error.
 * Any help is greatly appreciated!

 * I am not sure where to find an actual php.ini file, but have tried steps 2 and
   3 in the above post, and they do not appear to change to allowed memory size (
   the error message remains the same).
 * Any other ideas?
