Nginx server and ajax pager problem

Hi,

Views ajax pager works fine with Nginx webserver. But not in Quicktabs.
If I choose Ajax pager in Quicktabs module the links looks like:
http://madfanboy.com/views/ajax?page=0%2C0%2C0%2C0%2C1&view_name=Best_Month&view_display_id=block_1&view_args=

When I click in it I see the white page with some text.

If not, the link is:
http://mysite.com/node?page=0%2C1&js=1&view_name=Best_Week&view_display_id=block_1&view_path=node&view_base_path=null&view_dom_id=8&pager_element=1&view_args=
and it works perfectly.

So, I think I need to add something to the Nginx conf to make Ajax pager works with this module.

Thanks
