I got Plesk 7.1.2 (30 domans plan) from my providers. I upgraded that to plesk 7.1.6 successfully,. after sometime, i upgradded to 7.5.2 and got the notification that it started. during that installation process, i logged into my local webserver and the new server (on which the installation was in prgress, using SSH). by mistake i send the reboot command to the server on which the installation was going on instead of my local web server (that is my test server) Now all things works fine, but when i click on Upgrade, it hangs. Is there anyway to fix it? or roll it back to 7.1.6?
