Conflict between Ultimate Facebook and Event Espresso

Event Espresso (EE) is a full featured event management plugin and has even been recommended here in the past :slight_smile:

We just ran into an issue between EE and Ultimate Facebook (UFB) that prevents the EE event registration process from working. The only way I could get it to work, since I have UFB network activated, was to disable all features in UFB for the site running EE. The easiest way to reproduce the issue is to toggle OpenGraph feature on/off with EE active and try to register for an event.

The EE developer is thinking it might have something to do with the way UFB might be loading pages multiple times in order to retrieve data from FB that goes into the final page render (he observed this behavior with another FB plugin). If this is NOT the issue on UFB maybe there is something else causing a conflict.

Here is a full thread on the issue with more specific details:

I'm really interested in helping drive a solution here as I think both plugins are extremely valuable and it would be great if they could both work in tandem.

Thanks!
