I have already added some forums and groups some time ago but when I went to create a new forum yesterday nothing happened when I clicked Save, or Save and Continue. The screen just redraws with no confirmation of success or an error message. I have tried stepping through the code by putting breakpoints in CreateForum.cshtml but I cannot see anywhere that the code fails.

I have made some changes to nopCommerce but nothing to the forum side that I can remember except to the css and adding the rich text editor to the Create and Reply view, so I've changed something that affects it without realising. If anyone could give me suggestions to where the problem might be occurring, or if it is just a setting that I have changed in Admin that could affect the ability to add a forum I would be very grateful. Thank you.
