I tried to set up Ultimate Facebook so that users could register with Facebook.
On the registration page on our website, for our free membership option, when you click on the Signup option, the page changes so you see the registration fields and there is also a "Register with Facebook" button.
When you click the "Register with Facebook" button, the Facebook registration page appears to load/autopopulate correctly. However, when you click the "Register" button at the bottom, you get a message saying "Oops. Something went wrong. We're working on getting it fixed as soon as we can." (Please see attached screenshot.)
I have BuddyPress (which I added solely for the purpose of adding a field to the registration form for the non-Facebook users), Ultimate Facebook, and Membership 2 Pro.
I tried deactivating BuddyPress (to check for a possible conflict) but then I didn't even see a "Register with Facebook" option at all on the registration page.
When I go to Facebook -> Facebook Settings -> Facebook API, the green checkmark appears to say that it's successfully connected.
Please advise what I can do to fix this issue. Thank you!
