I've found this thread http://forum.parallels.com/showthre...-And-quot-Add-or-Remove-Components-quot-Pages that seems to be similar to my problem, The issue is that when i click the link to add or remove components from Plesk panel 11.0.9 it opens a new tab to this address https://myserver.com:8443/smb/update/add-components/ and then nothing happens... just a blank screen and it keeps loading forever. How can i solve this? It was working a few days ago
