I've followed the instructions for installing Mezzanine on Python anywhere (and already have another site using Mezzanine, though an older version) but am hitting a wall now.
I've been able to get the site working two separate times, but as soon as I add a test blog post I get the following error:
MultipleObjectsReturned: get() returned more than one Query
Any ideas? I'm at a loss what is going on.
