I'm using plesk reloaded 7.5 in my fedora core 2 server. My server was attacked by ddos then it's gone down. After that, I reboot it. And now, when I open my control panel page I get the error message like below: Unable to query: Can't find file: 'sessions.MYD' (errno: 2) 0: /usr/local/psa/admin/plib/common_func.php3:2 psaerror(string "Unable to query: Can't find file: 'sessions.MYD' (errno: 2)") 1: /usr/local/psa/admin/plib/class.Session.php:2 db_query(string "select * from sessions where sess_id="eccf45c0cef217f59417a50b00dbb694" and click_time >= NOW() - INTERVAL 1800 SECOND") 2: /usr/local/psa/admin/plib/class.Session.php:2 session->isexpired() 3: /usr/local/psa/admin/auto_prepend/auth.php3:2 session->init(string "220.127.116.11") I've search all the plesk support and FAQ but I really cannot find the solution. My server's plesk control panel is: https://18.104.22.168:8443 Thank for your reply. I'm sorry about my bad English.
