I am trying to edit the K2 User Group options. The page does not even load when I click on it. Running with Error reporting returns the following error.

Warning: require_once(/home/bgiradlh/public_html/usewes.com/theartlocation/administrator/components/com_k2/controllers/usergroups.php): failed to open stream: No such file or directory in /home/bgiradlh/public_html/usewes.com/theartlocation/administrator/components/com_k2/admin.k2.php on line 118

The corresponding line of code is

require_once (JPATH_COMPONENT.DS.'controllers'.DS.$controller.'.php');


Everything else in K2 seems to work fine. I am running Joomla 2.5.1

I was able to fix the problem by renaming the files in the controllers folder to remove all capital letters. I was able to reach the User Group view area. But when I went to click on create a new one I get this now.

Require_once will halt the rest of the file if the file is missing.

I reccomend doing a reinstall of k2.
