Plesk interface displays the below error:

HTTP Error 500.0 - Internal Server Error
<handler> scriptProcessor could not be found in <fastCGI> application configuration


'PleskContolPanel' Website is configured improperly. Some of the request handler points to the non-existing binary.


Make sure that all request handlers in 'PleskControlPanel' website have correct paths.

in case if this doesn't help, make sure that there is no 'web.config' file in the '%plesk_dir%\admin\htdocs' folder
