Moodle 2.6 Centos PHP 5.5
I think I am experiencing a bug with the View/grade all submissions page in the assignment module. When I attempt to access that page it is going to blank or sometimes it goes to a page without CSS. Firebug is showing an HTTP 500 Server errror.
Most teachers are not experiencing it - it may be because they are not loading as much data on the page. They are assigned to one group and the separated groups is enforced. But it is still very slow loading and the 500 error is concerning. Does anyone know what might be causing it. It was fine in 2.5.2
