I have a weird issue. My site works fine on QA and LIVE environments but I can not debug using localhost. It renders lot of weird characters as shown in the picture. This breaks the Javascript and site doesn't work at all.
I didn't have xmlns property in tag and after adding that some weird characters have gone but not all.
This started happening right after I upgraded my .Net framework to 4.5.2 and started using Visual Studio 2013.
I have few websites setup with same/similar code and JS libraries. They are working fine in my localhost.
Don't where the issue is. Any guidance will help.
