I have upgraded Moodle to the latest version via Softaculous and it has crashed the system, I am just lloing for someone to help me get it back online; i have tried restoring but alas it doesn't work.
Softalaculous is not provided or supported by moodle.org. We'll try to help if we can but we didn't write it or know how it was set up by your host. You might be better seeking help from whoever provided Softaculous to you.
Once again... THIS is why using these scripts is a bad idea
You will need to tell us more about how you tried to restore. Do you have a copy of the moodle database, moodledata folder, and even moodle?
Softaculous might fine for your very first install of Moodle, but we all kinds of problems with it whenever people try to upgrade. My guess is that Softaculous is just not smart enough to handle a rather simple task of upgrading, probably because of the many ways people modify their moodles.
