Hi Steve,
I just got them both working – the core plugin needed to be reinstalled too.
Question – did you happen to update the plugin recently? I have an auto-updater running on the site, and though it rarely give me problems, once in a blue moon an auto-update will mess up a feature. I’ve configured it just now so the Connections plugins will always require a manual update, but it would be good to have confirmation that was the likely culprit. My client swears they didn’t delete or deactivate anything. :)
