YES, I did it. RCR has messed something up again. Really all I was doing was adding new mentor ID badges in ftp--something I've done tons of times before and I was doing last night too--with no issues. I had to go to bed before I got them in all the themes, so continued this afternoon.
Now most of the menu is gone and the buttons to do things like post are unlabeled. If anyone is wondering I think it's the first button at the top of a thread or post on the right side--I got it by just clicking on that one and hoping!
To submit it is the first rectangle button at the bottom left of the post typing box--preview is the 2nd (middle) button at the bottom right.
I can't get to admin functions--or don't know if that menu button is available without a label. Can't approve posts.
Oh and if you post, you may be confused. I just posted this basic message at the mod board first and after selecting the supposed submit button it took me to a page with the header and stuff, but nothing else. Ugh, did my pots disappear? Nope, fortunately, the forum menu button is still there as are the breadcrumb links at the top showing which board and thread you are in. I selected the board, it took me to a normal looking board (without those menu buttons) and showed the post I had just created. So we can post, it just feels weird.
Going now to the smf help board to post this problem.
