Hi, After 3.1 upgrade from 3.0 all virtualhosts, ispconfig included, where inaccessibles. Then I restored the /etc backup to recover my hosts and noticed ispconfig was runing OK in version 3.1 so I kept the latest ispconfig version installed with the old /etc stuff. But now after a few weeks I can't login back to ispĉonfig panel. The /var/log/ispconfig/auth.log says "Successful login for user 'admin'" but the same login page always displays again with emptied fields. Nothing in ispconfig.log Any idea ?
