I've had a really strange thing happen and I REALLY need a fix. I was running the beta tester plugin because the new site I was working on REALLY needed the custom menus available in 3.0 beta. Once the version launched out of beta I uninstalled the beta testing plugin (WEEKS ago).
Today I got an update notice and updated only to discover the update was 3.1 beta with wp-admin tool bar. Ugh! This SO screws with things bigtime.
Why am I getting installs of betas when the beta tester plugin has been uninstalled?
