I am recently unable to add any new courses. When I try to add a course it displays the following error: "Error: The website encountered an unexpected error. Please try again later." The following message is logged whenever I try to add a course: OgException: There are no OG fields in entity taxonomy_term and bundle forums referencing node - course. in og_group() (line 2016 of C:\wamp\www\Opigno_Test\profiles\opigno_lms\modules\contrib\og\og.module). This all appeared to start happening around the time I deleted a course, but I am not sure if this is related. Anyone have any ideas what has gone wrong and/or what the solution is?
