I've read on the official Ghost website that running Ghost with Softaculous on CPanel installations is a disaster. I have to say I found that this was not the case and it was fine. Its a minor version behind the current release but when I did it as a test run on a CPanel box I had going spare it worked perfectly.
It is a bit unusual in that to restart Ghost you have to edit the installation and select restart. It also used a cron job for checking Ghost is still running which again is unusual but did do the job.
I felt a bit sorry for Softaculous as they clearly put a lot of effort into fixing the problem. Alternativly it could be there are good cPanel hosts like NameCheap and very bad ones who overload their servers or don't support all the functions.
