Issues with plugin loading scripts

When using this marketplace install, certain plugins (namely Breakdance builder) fail to load internal scripts.
Their team have been able to copy the site to a different server and not had any issues - so it's something to do with the Azure setup side of things.


Cannot see any way to ensure the variable gets populated, and embedding the scripts manually in the header of the site causes a HTTPS error (and also doesn't resolve the issue!)
