No. This is the latest release, Not git snapshot

Please try python manage.py migrate --list that will show the list of migrations and which ones are pending, there must be some that have not been applied after you updated the code. And to apply any pending migrations - just type python manage.py migrate.

I'm seeing this issue too when trying to update settings. Did you ever find a root cause? I have a fresh install (followed instructions from your docs) , on a freshly installed system. Sometimes i don't see the error at all, but when i try to 'save' settings, the page appears to refresh but the setting doesn't appear to have actually changed... not sure what's going on, it's late but just wanted to see for now if you've seen this again since this question came up a while ago...

Did you use askbot-setup to create the project? Please feel free to email me your settings.py file at evgeny.fadeev@gmail.com. We had this problem before, but I don't remember how we overcame it. Possibly there is some missing dependency and the db transaction error is masking the real issue.
