Hi,
I am seeing a similar problem.
Below is the settings file and the stack trace.
This error seems to come and go. I don't make any changes and it
appears and then goes without any change.
It seems to have to do with writing to the database.
Can someone explain what the error is to help me
I suddenly started to get this error... but never changed this
setting. This error is critical and causing my entire site to crash.
The DATABASE_ENGINE was set to 'dummy'. I have also tried to set it
to 'appengine', neither seems to be working.
