Wordpress 301 Moved Permanent Response to Jquery.post Request

Question

I have lost my hope of finding a solution to my problem, I hope someone can help me here. Here's the problem:

I have a wordpress installation with an extra wp_lojas table (for stores). Customers can go to the site and through the form, put their address and use Google Maps Api, find stores near them.

When a user submits a form, I check its address position (latitude / longitude), and through an SQL query, I look for the nearest stores.

The form sends the parameters (latitude / longitude / radius) through the ajax request ($ .post ()) to the php file that is inside my theme folder (/wp-content/themes/accessorize/dadosLojas.php) and this file creates XML with found repositories.

Everything works fine offline, on my local machine. On the net, I get the answer "301 moved forever." If you guys installed Firebug and want to try it, the test link is http://www.colletivo.com.br/accessorize/ and the form is located on the page footer. If you want to get the address from Brazil, try "Rua Vicente Leporace, 1534".

If you do not understand what I was trying to explain, or if you need more information, please let me know.

Many thanks.
