UPDATES:

Implemented developer branding info (Brand Color, support email/webpage) from the Tools > Branding section to display directly on the GUI.

Logo can be added to this as well by simply adding your logo named "SoundSyncLogo" to the image pool. The script will auto-detect if the logo is present. If you dont have a logo added to the project, it will display initials for your Brand (example: SS for SoundSync) instead.

I got it to work nicely in my project

I’m not at my computer but I can say:

start url has to be empty if you don’t want weird behaviour (I reckon there’s a slash by default, it should be removed) I don’t remember the next property but name but place de full url in there exported files have to be placed in a subfolder called cache on the server, but don’t include /cache in the url.

Here it works smoothly
