JQuery Error: Uncaught TypeError: Object #<HTMLDocument> has no method 'ready'

Apparently you are using both jQuery and Mootools and both of them do use $ as an alias to a core function. Probably the $ function which is generating this error is the Mootools function. I'd suggest you to try to write your jQuery code using jQuery instead of $ so you can confirm my point is right or not.

Good luck!

Yup - I believe that's exactly the problem. jQuery and mooTools fight over the use of the $ notation.

You're on the right track with using

try{
   jQuery.noConflict();
 } catch(e){};

But after you use that, in order to use jQuery functionality, you have to call it jQuery(...) instead of $(...). Example:

// Use jQuery via jQuery(...)
 jQuery(document).ready(function(){
   jQuery("div").hide();
 });
