jQuery DOM issue - very frustrated!

jQuery DOM issue - very frustrated!

Hi there

Sometimes when I attempt to click on a link to a page all that the page returns is a JSON string and not the HTML of the page itself (In IE, FF and Chrome).

the apache logs show a normal "200" page response.

Why would a page just display the JSON string and not the entire page (with the JSON information placed in the DOM.. using.html..?)

I would really appreciate some advice, as Firebug shows no issues as far as I can see, but the browser just displays the pure JSON string!

Thanks!
