Jeff,
glad to hear the 404 errors are fixed.
You said:
Yes I did uninstall on the plugins overview page. It seemed as though that was the only way I could get the TaskChains and HotPots to work again without the 404 error. It is not a big deal. It is very easy to recreate a TaskChain. I have all my HotPots foldered together according to topic. It is a matter of zipping them and resetting the conditions.
I have split off the discussion about "Free access after specified grade" into another thread:
regards
Gordon
