I posted this on the Moodle installation problems forum but I want to post it here in case someone finds it by search or otherwise. Here is the post in its entirety…
I am posting this for anyone else who might run into this scenario.
I upgraded from 1.7+ to 1.8.2 and when I went into my courses and turned editing on, it returned a blank page. Needless to say, I freaked out.
I combed the forums and figured out that a lot of folks have this problem due to incompatible blocks or activities. I didn’t think I had any of these installed.
Turns out I did.
It wasn’t one I thought it would be, but when I went into debugging mode it returned an incompatible block.
I deleted it from both activities and the blocks and the site works fine. Maybe this will help someone else.
