I was logged for a couple of days, everything working fine and no changes to my system. I tried to see active items and got this error

It is highly unlikely that nothing changed in your system… unless of course the Trac server is not located on your system.

The server must have been started in an environment from where the Python bindings for Subversion couldn't be loaded. If this didn't happen before, it's:

• either because the bindings were previously available
• or because they were not used, which is the case as long as no repository_dir is configured in the TracIni
