My server (Plesk 2.5 running on RH 7.1)has been running solid for the past 30 days and it went down sometime earlier 2day. Anyways, i have a feeling that it might have been hacked...i had a RS tech rebooted the machine...but now none of my domains are showing up when i type in their URL. When I log onto Plesk as an administrator all of my domains are gone...it keeps giving the following error:

"Unable to define domain list: Got error 127 from table handler"..


What should I do?
