When you go to the module studio in our instance of Sugar I get this error:

Warning: aSubPanel::include_once() [function.include]: Failed opening '' for inclusion (include_path='/var/www/sugar/include/..:.:/usr/share/php:/usr/share/pear') in /var/www/sugar/include/SubPanel/SubPanelDefinitions.php on line 337

Fatal error: Class name must be a valid object or a string in /var/www/sugar/include/SubPanel/SubPanelDefinitions.php on line 338

The entire custom folder is owned by the server and set to 775. Any suggestions or help is greatly appreciated.
