@mether, do you remember how we solved this?

You logged in and fixed something and then later fixed it in Askbot as well. It was some bug.

The result? 'impossible to use livesettings without memcached' ... we found it out on our own, but the livesettings author confirms it to be the case too.

"If the cache backend configuration is "locmem", it works good only with development server. For production with multiprocess deployment it is necessary to use memcached, otherwise old values can be randomly used so long, until the CACHE_TIMEOUT expires. It is very annoying if a change have been saved and shortly other change should be submitted, because the old vaue can remain in the form and be resubmitted back."

We'll help you with more detail tomorrow, but possibly you are behind on migrations or dependencies. Did you take code from github?

No. This is the latest release, Not git snapshot

Please try python 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 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 file at 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.
