Why would my server not properly link to only one file on the server, but fine on all the others?

I originally posted this question on the code review forum, but was directed back to StackOverflow.

One contributor said that it was a problem with my Apache/server setup, but why only is one .js file affected? Problem described here:

I am a bit of a jQuery raven, I learn and take as needed forage about, and have no formal education, so your patience is appreciated.

I have a main issue that a jQuery plugin is not working on the server, but works locally.

I have checked for the usual oversights (having relative links not on the server, having all the required files on the server & case sensitivity issues), but it still wouldn't work.

I am not fluent in the FireFox debugging tools either, however I found a enormous anamoly which I suspect is causing the issue.

The plugin code is in it's own .js file, and in the "debugger" in firefox, when I click on the appropriate file, instead of previewing the .js file, it shows me the index PHP/HTML of the root for the domain.

For specific, real examples:

Example page where the plugin is failing: Here

Here are the error messages that I get under the "Console" tab in FireFoxe's tools:

SyntaxError: syntax error @ http://bcw.se/3point0/js2013/imageScroller.js:1

TypeError: $(...).tinyscrollbar is not a function @ http://bcw.se/3point0/index_debug_crousel_02.html:75

Use of Mutation Events is deprecated. Use MutationObserver instead. @ http://code.jquery.com/jquery-latest.js:3492

And I presume the first two errors above are due to the anamoly and causing the failure, not directing properly to the right .js file, see screen dump below:

Can anyone help and is this the right forum?

Thanks in advance.

Your file is called ImageScroller.js and not imageScroller.js. Change that and it should work. (Apache should be case sensitive)

As imageScroller.js doesn't exist the url gets rewritten to the index page (probably by your .htaccess RewriteRule).

And the origin of the syntax error is kinda obvious - The browser tries to parse the fetched "js" file as JavaScript. But just isn't valid JavaScript ;).
