As and when you come across this error on Plesk, you can fix the issue. Follow the steps mentioned below:
  • The first thing you need to do is copy the libmysql.dll file from the destination.

  • Then, you need to add the PHP Path at the very beginning of environment variable “Path”. The path to add is highlighted. So make the following changes:
Path = C:\Php;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\Intel\DMIX;C:\Php;

If the problem is with ZendOptimizer, try another version.
