Getting warnings when using Gravity Forms + bbPress

Hey guys,

Wondering if anyone might be able to tell me what's going on here …

I'm using Gravity Forms for user / store registration at, and things seem to work with the exception of the warnings occurring (screenshots). I'm guessing that's why it takes 20 – 30 seconds for the page to process the request, but I'm not sure.

Not sure why bbPress even comes up … I'm not even focused on that now – but the plugin is installed because I have interest in expanding on it later.
