I plain ran out of time and energy to work on PyBlosxom, so I stepped down as maintainer. I'll stay on the project as an occasional developer.
I went through my plugins and discovered wbgpager had a bug in it that prevented it from working with PyBlosxom 1.2. So I fixed it and released wbgpager 1.2. You can find it here with all the other plugins I've done. I also made some fixes to some of the other plugins. So if you're using anything I wrote, you might want to check to see if there are new versions.
