Fix module for category search in Prestashop

Hi, I need to fix my module for "step by step" search of products in my website [login to view URL] - located on the left side. After filter there is nothing happened. There is error because of my old module for clean URL (no ID of category and product) which makes change in override. I need to keep my old module for clean URL and also want to make this new module to be working. Is somebody able to fix it?
