Hello, I don't know what is happening, but when I edit a course via dashboard it is not possible to connect a forum to my course. This is recently happening, it was not happening this, perhaps it is a bug.
Even I have some forums (pic: http://prntscr.com/8ra218) they do not appear to be selected when editing (pic: http://prntscr.com/8ra2hi).
Please, help me with this.
Thanks a lot,
Diego
