Looks like it works after I turned on the settings under UsersWP > Social. Profile photo is also being pulled into the user account now. Thank youuu!!!
Anyway, regarding the error, I actually keyed in my facebook email and password and it directed me to the error page (it is a valid email and password though). Does the error occur if the email is invalid? Just trying to understand here just so I don’t repeat the same mistake again 🙂
