Cause

The plesk-ui-library package is installed from the wrong repository, or was not updated correctly.

Resolution

1. Connect to the server via SSH

2. Check that the package and source version match the current Plesk version

   # rpm -qi $(rpm -qa | grep plesk-ui-library) | grep "Name\|Version\|Release\|Source"
   Name : plesk-ui-library
   Version : 18.0
   Release : 2.centos.7+p18.0.34.2+t210325.1052
   Source RPM : plesk-ui-library-18.0-2.centos.7+p18.0.34.2+t210325.1052.src.rpm

3. Reinstall the package to get the correct version:

   Note: Replace the version number in the following link with the same one as in Plesk

   # rpm -Uvh --force --nodeps http://autoinstall.plesk.com/PSA_18.0.35/dist-rpm-CentOS-7-x86_64/base/plesk-ui-library-18.0-2.centos.7+p18.0.35.2+t210526.1158.noarch.rpm
