I got this Fatal Error whenever I go to System > Permissions > Roles and Click any Role.
Fatal error: Class 'Mage_Magentix_Fee_Helper_Data' not found in /public_html/app/Mage.php on line 547
but I can locate this:
/app/code/local/Magentix/Fee/Helper/Data.php
What could be the possible solution to this?
