You don't have any sites. Create with Plesk Problem



I need some we have a VPS and on that server there are three domain currently hosted and running.

3 weeks ago I've had some issue with plesk site, shows that "You don't have any sites.
Create with Plesk" along with this the 3 domains will not be working as well and if we visit the websites it will show internal server error.


The plesk site disappearing daily from 12 Noon and i have to restore our backup everyday to make the website working.


Is there anyone having the same issue with the plesk?
