Softaculicious or quickinstall or whatever, they are all the same. A quick installer for cms's and LMS,s and others on hosted websites. Problems arrive when hosts don't have the latest PHP for moodle and other software. More often than not, hosts provide dated moodles as far back as 2.62.
If you have a problem with softaculicious, the only one who can help you is your host. Best way is to ensure your host has the the latest PHP and install it yourself. If your host refuses, change your host.
