Hello, We have updated iRedAdmin from 1.0 to 1.1, and then from 1.1 to 1.2. It says: "* Upgrading completed." with no errors.

When logging with postmaster@*** (Global admin) we have no problems, and all works great.

But we have problem with existing and new domain admins. We use these 2 sql commands for adding:
sql> USE vmail;
sql> UPDATE mailbox SET isadmin=1, isglobaladmin=0 WHERE username='smith@test.com';
sql> INSERT INTO domain_admins (username, domain) VALUES ('smith@test.com', 'test.com');

When domain admin try to log on to server, after entry username/password, we got error:
###
The page isn’t redirecting properly.
An error occurred during a connection to ***.
This problem can sometimes be caused by disabling or refusing to accept cookies.
###

We tried using other browsers, private browsing etc, but it's a same error.

What can be a problem?

Thanks in advance,
