E-Mails stopped working for new users

Hello, I recently faced problem with dovecot. When creating new users for domain.com you can’t login, but earlier created users can login without any issue. here’s dovecot debug log:

P.S querying directly in MySQL command line resulting that entry exists but dovecot says unknown user.

Version was 1.7, upgraded to 1.7 Build 2 problem exists…

Thanks in addvance

P.P.S Also I figured out that FTP Accounts are doing the same damn thing…
