I had a problem where after installing a mod, The "Admin Access Management" controls were gone from the admin page menus. I finaly forund that a mod over written the cart side "includes/filenames.php" the overwright file was not as new as the fresh install. I replaced the filenames .php and The "Admin Access Management" controls came back. this worked for me hope its your solution also
