thanks for your reply m8 but it came a little late coz i did it but not 100% working and i need to uninstall it to do it your way
i found this way to uninstall it but don't understand how after trying many ways;
Full Plesk uninstallation;
Download the script and run it with root privileges on your Linux server:
i have the script downloaded. should i unzip it or not and where in the server i should upload and how to run it???
i feel awful when typing coz i'm good at many things but when it comes to this i feel duuuuuumb
PS this is taken from here:
