TOPIC: Broken javascript

Since installing the extension, my other javascripts won't work on my site.
They will work to start with but once I visit the events page all the js breaks. My rotating header image won't show etc,

Any idea as how to fix?
I'm running joomla 2.5.7
the url is www.cyclingchb.co.nz/site/index.php
use this link as I have a index.htm showing at the moment with a site down message.

I'm using the Joomlashine epic template

This has seemed to come right by itself. however I still get a "out of memory at line: 16" error when I goto the events page and it only happens in IE 8 (I'm not sure about IE9)

My php memory has been increased to 128Mb
Any Ideas as to why this error?
