PleskMainDBException issue

SigveR

New Pleskian
Hi.

I can't access my Plesk panel because of the following error:

Code:
ERROR: PleskMainDBException: No connection could be made because the target machine actively refused it.
(db.php:435)

Search for related Knowledge Base articles

I clicked the link at the bottom that referred me to the knowledge base, but I can't figure out how to complete the provided steps.

For example "Resolution: Start the "Plesk SQL Server"". How do i start the Plesk SQL Server..?

I also tried to use the Plesk Reconfigurator, but the following message applies: "Can't connect to database on localhost(0)".

Any ideas..?

Just click on "Parallels Plesk Panel Service Monitor" icon in Windows Tray (near clock in right-down corner), select "Plesk SQL Server" and click Start button.

Hm.. I did and got this error message: "The process terminated unexpectedly Error code 1067. "
 
Looks like something wrong with SQL server. Contact Support Team if you can't troubleshoot it by yourself.
 
I´m experiencing today exactly the same problem. Any help?
