"This script is only accessible from localhost." BackBee

Hi Folks, I’m stuck.

I’m attempting to install BackBee CMS on a VPS.

I’ve installed composer globally and it’s playing nice in SSH.

I’ve run the command:
composer create-project “backbee/backbee-standard” /path/to/your/folder “1.0” -n

Which appears to work.

But when I try to run mysite.com/public/install.php, I get the above message in the browser.

I’m out of my depth, any ideas? Thanks very much for looking.
