18Jul Plesk Control Panel icons missing!
Scenario:- Add Application icon missing or grayed out
“Add New Application” icon can be missing if “Hide all greyed out buttons by default” is enabled on the Server -> Interface management page in Plesk CP.
“Add New Application” can be greyed out if some application is already installed in the domains’ DocumentRoot folder (httpdocs or httpsdocs). It is impossible to add another application in this case because of possible applications conflict.
