I was able to scan the site with Sonar. It's odd that Insight is being tripped up.

Yes, Sonar works fine here as well.
As for the script error, all scripts are handled by SD and the standard components. Even if I wanted, the only way to interfere would be manually editing in HTML Editor before uploading the exported site.

I found something interesting!
If you select in preferences only Mozilla and the latest FF version, than it works!

I wonder if it's the form causing the issue.That's the only place I see any cookie setting possibilities.
