It seems you are using an old version of the plugin in which the problem arose back then. What version are you using?
MyBB 1.6.16
and
MyFacebook Connect (2.0.1)
thank sir its works
dear how can setup that user facebook password active for user when they register with myfacebook connect
Explain your request in proper english please. I can't understand.
i mean pm password not work .
and how can i do that if user someone register from myfacebook connect this user facebook password is future password of my forum
The PM functionality works fine on a fresh copy. Maybe you have a customized one? Just guessing as there's little I can do without a complete error report.
I still can't understand your request.
