Once I was trying to install a mod manually into forum theme and and my forum theme became corrupted. The home page just wouldn't load anymore. Thankfully, I had a copy of the page open (the one i'd been editing before) and simply copy/pasted the section that had been deleted back into the proper area and clicked save. There was a few tense moments, but I didn't freak out and things worked out fine. Did you ever mess up your forum theme trying to edit to insert code? How did you rescue the situation? Did you have to upload another copy of the theme?
