Hi I hope i'm in the right place ... in case not ... sorry, my first time. Few days ago i was connected to my ubuntu server in ssh and i made a mistake in the changing of the authorization. I repaired many of them and all the services is back and working well ... excepting PLESK and i can't find where is the problem. In case here is the message on the web interface when i'm trying to connect on ------ Server error (code 500): Exception with message 'SQLSTATE[HY000]  unable to open database file' caught at top level. ------ Of course, i checked the access on the sql database and everything working well even thought website and ssh connection. So the dilemma is reinstall plesk or find the error. I'm not closed to the reinstall solution but even if i have a backup, i would prefer to don't have to reinstall all the data because all of them should be sent by ftp thought an ADSL connection ... so at least 2 days of transferring. So in case i reinstall PLESK with the command ------- /usr/local/psa/admin/sbin/autoinstaller --all-versions --web-interface ------- will i lose all the data (website, mail and config) on the server? Thank you for your help.
