Need a good method to troubleshoot javascript in a difficult situation

Question

I am tasked with figuring out why the jquery slider will not function. I know that it worked shortly after installation because I was checking the browser. The only reasonable conclusion I can come up with is that there is a JavaScript library that conflicts with the fact that there are too many of them in WAY.

I have no control over removing JS calls from the header, as this is too complex an extremely limiting CMS ...

Does anyone know a good way to resolve JavaScript conflicts using firebug or any other tools / methods? I can’t just delete them in the firebug HTML editor, since this will require a correct page reload?

Here's a bug from Google Chrome *

Resource interpreted as script but transferred with MIME type text/html.
Resource interpreted as image but transferred with MIME type text/plain.
11:02:44 (0ms): global: Logger output to the function console.log() has been enabled.
frame: [object HTMLIFrameElement]
frame: [object HTMLIFrameElement]
frame: [object HTMLIFrameElement]

Unfortunately, this does not mean anything to me.

Answer 1

I would copy the markup, add a basic tag to handle relative links and start deconstructing the clutter to find the culprit (using a regular array of debugging tools).
