User Registration problems

Hello

I'm using last Joomla last cb and installed right now cbsubs & plugin conditional
I tried some settings but can't go further because a registration problem :
I created a new user using the normal registration procedure with mail and approoving
But once approoved the user can't log in :

Erreur
Identifiant ou mot de passe incorrect. Essayez de nouveau.

neither can't request a new password :
the first times I got a danger message saying that this user is not known
and since i disabled cbsubs and conditional there is no message at all but no mail received

I really can't see why one of the 2 plugins mixed up my registration process - please I need some help here !

The error is saying your username or password is wrong. Neither plugins mess with either of those unless you hid those fields with a condition. The email process is modified by CBSubs though. By default emails don't send until after payment, but you can change this on the workflows tab of your plans.
