I am working with a joomla site and I installed a component named qcontacts. It works perfectly, but when I enable sef in joomla I get:

All the other menus in the site work properly with seo enabled with com_content, the problem is only with qcontancts. Any suggestions?
i actualy commented out from “components/com_content/router.php” the following lines
and everything seems to be working fine with sef. I am not sure if i did the correct thing or if i have any sideefects in the futre. But for now everything seems to be working.
