On my site with professional theme the regular search function works perfect. If I type the key word "ford" in and click the search button I can see the path in the bottom of the browser *http://mydomane.com/puplic_html/search.php?query=ford&type=all&mode=search* and I get the results of the search.
If I go to advanced search and type the same thing for a key word I get this as a path. *http://mydomane.com/puplic_html/search.php* with no query string attached and the page just loops right back to where I started.

Anybody have any ideas as to why it wont do the search.
