Going out on a bit of a limb here, not really expecting anyone to be able to help:
I have a site I set up with WB some years ago, currently version 2.12.2 r379. I have the Teams module installed, v1.4.1. It is working OK until I try to change it. I am unable to open existing entries to modify or new entries to add.
I'm guessing probably too old for anyone to know much about it, but just asking anyway.
