We have a problem to change the password via the edit profile page (like domain.de/profil/?edit_user=1 ).
There are the fields “old password” and “password” and – no matter whats filled in the two fields – the error “Password Fields do not macth!” (what should be “match” by the way) occured.
I found nothing about this issue in the forum.
We have wordpress version 4.3 and pie register 2.0.17.
In order to change the password you need to provide your current password (old password) and then you need to enter the new password in both password and confirm password fields.
