Nginx and Quicktabs = Ajax problem

Hi,

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

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

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

Any idea how I can resolve this issue?

Thanks
