I've been trying to either:
- reset password for my old Work account that has multiple WindowMizer licences.
- Register a NEW E-mail / User for another Work account that will be buying multiple WM6 licences.
RESET PASSWORD ISSUE:
- Email comes through fine, new strongest (reasonable) password inserted. Won't take it.
NEW REGISTRATION ISSUE:
There's a php within Chrome on Desktop that doesn't allow me to Submit the registration, or go further.
Note the locked-off Notification screen (bottom right) thing that can't be accessed, no matter how big one's monitors, how many monitors one has, or accessing on Chrome, Firefox or Safari. Screenshot is from Chrome.

You may need to update your phpBB version potentially, on top of everything else no doubt piled on you with WM6 development.
