Hi,
Not sure what changed in my hosting environment, but when I upgraded an
extension (mercurial plugin that was failing), trac ceased to work saying
it cannot load Python bindings for PostgreSQL. But everything was workihg
before.
I have psycopg2 installed. Trac was working.
Tried upgrading to latest trac. Still broken.
Note that I can load psycopg2 from a python prompt. I can also run without
errors when I create an environment manually in a python shell.
The log posted below mentions exception while checking for upgrade. Is it
possible to disable the upgrade checking to see if it's related to that?
There is also an AttributeError in AdminModule.
Can anybody help ? Thanks.
David.
Here is the relevant part of my log:
