Hello! I get this error and maybe my environment has a problem? I hope someone will give me a hint to solve this error.

Thanks a lot Michael

The tip of the plugin repository has been updated for the Trac 1.0 DB API. I'm sure it won't work in 0.11 and have no way of testing it in 0.12. I believe there is a note in the repo about what the last version to support 0.xx is. I suggest checking out that version and trying it to see if it fixes your problem. All the changes after that so far are about DB access. If I could figure out how to create a branch in SVN (I'm a git guy), I'd create a 0.11 branch so this was less of a problem. Sorry.

It won't work in 0.12 either, 0.12 had a different DB API: ​trac:TracDev/DatabaseApi#Trac0.12API. The pre-0.12 and 0.12 DB APIs worked with Trac all the way up until 1.1.2 though.

As for the SVN challenges, I wish I could help, but knowing SVN is just something one is born with and can't be imparted ;)
