Resolution
It is necessary to update Parallels Panel web-engine:

1. Download the appropriate package using the wget utility. Example for CentOS 5 x86:

#wget -c http://kb.parallels.com/Attachments/12669/Attachments/sw-cp-server-1.0-6.201004011105.centos5.i386.rpm

2. Install the downloaded package. Example for CentOS 5 x86:
#rpm -Uhv sw-cp-server-1.0-6.201004011105.centos5.i386.rpm

You need to get appropriate rpm as per your server architecture and distribution.
