Hello!
Our clients keep saving the email not the user name like previous version as the login information . This cauese the result that you every time need to erase the email and change to the user name or we cannot login .

How can we go back to the old ways where it saves the login name not the email that is usless since we cannot use it for login.

Yes, I have added it to system>>register>>user>>user standard ID and I have ticked the system>>settings>>standard ID client tickbox.
