Original sites on OLD SiteGround hosting. NEW demo probably on NEW SiteGround hosting. So demo of moodle? Did they allow you to see or do many things in the admin area of that demo site? ... like check environment, etc.
Was the demo site installed by SG folks NOT using Softacoulous or other infamous '1 click installers'?
Hosting providers usually do NOT go into the depths of application trouble shooting/fixing issues.
Heck, you might have to point them to Moodle docs on how to turn on debugging.
Oh, well ... to each their own. ;)
