Because of that the SEF system of Joomla cannot retrieve the necessary information from the URL and produce that error. You have two solutions: 1. You deactivate the SEF in the joomla configuration 2. You fix that menu option in your module and make sure that you have a valid categories listing menu selected (you might need to flush your website cache if you have any).
