I am using Moodle 2.4.1 and students are receiving this error message when submitting assignments as pdf's:
Coding error detected, it must be fixed by a programmer: Could not load preference popup_provider_mod_assign_assign_notification_permitted. Make sure the component and name you supplied to message_send() are valid.
More information about this error
The submittal seems to take place anyway. Any help would be appreciated.
