Customizer URL problem

[Studio384]

When you use the Customizer and hit the "Compile and Download" button, the menu breaks.

What do you mean by "the menu"?

[Studio384]

The navbar on top of the page, the links are relative, however, when you click the button the url of this page changes to http://getbootstrap.com/customize/undefined/customize/?id=7258922, making the links to send you to http://getbootstrap.com/customize/undefined/getting-started, and, of course, there is no page there.

@Studio384 I am unable to reproduce with Chrome on Mac. What web browser and OS (and versions) are you using?

[Studio384]

Internet Explorer in Windows 8.1.

If you could try and pinpoint where the JS that changes the URL goes awry, that would be most helpful.

The problem is with the use of window.location.origin in customizer.js#L59 which isn't available in IE.

This Stack Overflow question says to do something like this to support all browsers

if (!window.location.origin)
     window.location.origin = window.location.protocol+"//"+window.location.host;
