You have either installed a SVN version or updated to a SVN version on your server before and now you installed a stable update which is not compatible with the svn version that you have installed. So your problem is not a problem with ISPConfig 18.104.22.168, you just tried to update to a incompatible version as the version that you had already installed had more database tables then the 22.214.171.124 update. Never use SVN versions on production systems!
You most likely lost your database now, please restore the database from an backup. If you dont have a backup take a look at the /root/ directory, ispconfig stores a backup of the database there before the update is performed.
If you installed or updated to svn at any time before, you can not install any released version on your system anymore.
