Hi,
I'm not sure if this has already been mentioned or if it has been brought up already (I tried doing a search beforehand on the forums but it came up blank) but you are not able to do a fresh install of Totara 2.2. I tried setting one up just to test and it just sat there with a "Database can't be read" error and in the error logs it said something about mdl_config not existing.
I was able to create an empty Totara 1.1 instance and then upgrading to Totara 2.2 though. Just thought people might like to know.
