I had this ticket open in my browser and was about to take a look!

Basically, it seems like you have a couple of problems (almost there).

Firstly, you have some JavaScript errors in your console. Take a look using something like firebug and see, but you have JavaScript errors on that page (and probably others) throughout the site.

When there is a JavaScript error, this sometimes prevents other JavaScript from running – such as the S&F Ajax. So the errors you have must be fixed first – otherwise this will be near impossible to resolve. If for now this means disabling some plugins I would suggest to do that – even just to see if this is really the issue.

Secondly, it appears your Ajax Results Container may be wrong – it is set to the default #content but this really is a theme dependent setting – from looking at your code I’m guessing it should be something like main.content.

Let me know when you managed to fix or disable plugins that were causing your JS errors and we can move on to the next step (this may actually resolve your issues).

Thanks
