we have a standalone ispconfig on an old debian 8.2 . the server had a disk full problem, then resolved and rebooted. after that no way to login to ispconfig gui. it always come back to login page. we changed browser, computer, cleared cache, changed password in db, but still nothing. any help?
Probably the MySQL DB is corrupted. Run an optimization and repair on all tables of the dbispconfig database using phpmyadmin or on the shell.
