You're welcome. I'm interested to hear how you resolve the issue.

>What I noticed - just now - is that when the project is being run/debugged - a section Script Documents appeared right below the Solution in the Solution Explorer. And in this Script Documents are (I am more or less entering it here to document for myself):
>Script Documents
> Windows Internet Explorer
> MyLogIn.aspx?ReturnUrl=/Default.aspx
> modernizr-2.5.3.js
> jquery-1.7.1.js
> bootstrap.js
> MyLogIn.aspx?ReturnUrl=/bundles... and then the long line that points to the error.

I also just read on Stackoverflow that the problem could be with the Microsoft Asp.net Web Optimization Framework. So I will need to find out if I have the correct version. And if not, to update it.
