I’m glad you are up and running again. It’s a pity that we couldn’t identify the ultimate issue. But thanks for discovering the Connect tab JavaScript bug; I will include the altered file in the next release.
If you would like, I can install the plug-in and we can continue to troubleshoot. I just need to know what to do next, but we can continue.
The bug you encountered smells like one that you probably couldn’t reproduce even if you tried. I wouldn’t be game to mess with your working system and risk breaking it permanently.
