Ok, my forums run 1.1.5 (I know 1.2.0 is out, I'm working on it).
I was upgrading an add-on when the page went blank and says server error. I searched this website for some help and found that "rebuilding master data" may help. I tried that, no luck. Still can't get anywhere.
I haven't really learned a lot about troubleshooting this software yet, but I do know enough to do so if given some direction on where/how to start.
Thanks in advance,
