Hello, I clicked to upgrade our Plesk from 7.5.2 to 7.5.3 in the panel. After about 2 hours, the Plesk panel was still unresponsive, so I restarted the server , and now it doesn't boot at all. Our server is running Linux Fedora core. Booting with the rescue images works. Is their anything I can do other than reimaging the serer? Thanks.
