I have been making some changes and updates on the backend and hopefully haven't changed something important that actually has an unintended effect of maybe preventing access into a forum or making a post, or something else that I can't imagine.
If this, or something, has happened, please comment here and I will get it fixed. Whatever might have happened, is not an intentional change - I am just trying to clean up some coding and simplify some settings - nothing should actually change.
