Due to several Shared Hosting environments being incompatible with Ghost due to memory issues while installing Nodejs/Ghost we have set Ghost to be disabled by default and if you as a server admin would like to enable it you can enable it from Softaculous Admin panel -> Software
You can refer to the following guide on how to enable scripts :
http://www.softaculous.com/docs/Enable/Disable_Scripts
We will still be maintaining the updates for Ghost package, so if you have enabled it you will receive the updates regularly.
