Wordpress Q2A installation shows junk characters

Question

I installed the q2a and integrated it with my existing wordpress installation which is on nginx and i am unable to get q2a showup properly under the root directory where it is installed, http://domain.com/ask/ as it returns junk characters. While domain.com/ask/index.php works well. Is it to do with my nginx config?

Have you tried with :
      gzip_http_version 1.0
      add_header Vary Accept-Encoding
in your nginx conf ?

Thanks to your pointer found out it was due to q2a compressing output. I now disabled compression as I could not really make nginx work properly with compression enabled with the headers you gave.
