Question

While install q&a struck in the page http://www.expertpanda.com/index.php?qa=install and nothing happens

Answer 1

The header sent back when you click the button is: 406 Not Acceptable

Your backend service is saying that the response type it is returning is not provided in the Accept-Type HTTP header in your Client request.

Ref: http://en.wikipedia.org/wiki/List_of_HTTP_header_fields

1. Find out the response (content type) returned by Service.
2. Provide this (content type) in your request Accept header.

...

406 happens when the server cannot respond with the accept-header specified in the request. In your case it seems application/json for the response may not be acceptable to the server.
