  • Support for BIND DNS has been removed from Plesk for Windows due to security and maintenance risks.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS.

Basic Pleskian
Hello,

I'm using plesk 9.5.4 when I enter the plesk url I give this error:

ERROR: PleskMainDBException
DB query failed: Unknown error

0: common_func.php3:171
db_query(string 'set names utf8')
1: common_func.php3:626
reconnect()
2: common_func.php3:591
db_connect()
3: auth.php3:90

I done this article:
http://kb.parallels.com/en/115602
but there is problem yet, I see administrator pass plesk and I can login to plesk mysql with same password but plesk has problem.
I restart all services and finally reset the server but problem doesn't resolve.

Please guide me
