Known Issues
Problems with MySQL databases and PLESK 9 after upgrade
If you get the following error after upgrading when you try to log into PLESK then you need to upgrade your database tables:
ERROR: PleskFatalException bad column in table: `backup_time` time NOT NULL default '00:00:00', [...]
Issue the following command from the shell:
mysqlcheck --check-upgrade --all-databases --auto-repair -uadmin -pyouradminpassword
followed by:
cat /usr/share/mysql/mysql_fix_privilege_tables.sql | /usr/bin/mysql --no-defaults --force --user=admin --password=youradminpassword --host=localhost --database=mysql
This script updates all the mysql privilege tables to be usable by the current version of MySQL.
