1 bug + 1/2 bug
I found two problems with the user profile when saving (Vanilla 2.1.3).
1) The module Profile Extender, type "birthday" field without required to fill it prevents to save the form. => Display : ValidateDate
2) Vanilla does not differentiate between two users: Clément & clement
I did the migration from phpBB. Unable to save the form.
Thank you for your help.
