title: OpenCart - 404 page not found error with new module
body: <p>OpenCart 1.5.6; Theme: Default.</p>
  
  <p>I've created a new module 'Seller' cloned by 'Manufacturer' ... Admin side &amp; Front side is working okay, means adding / editing / saving data is working okay, except an issue.</p>
  
  <p>When I click on 'Seller' link at product page (frontend), it shows 404 error / page not found, ideally it should work same as Manufacturer module works, should open seller's page with list of products by the same seller.</p>
  
  <p>What could be the reason? Because I don't see any error in log files / VQMOD, it just shows 404 error.</p>
  
  <p>Any clue?</p>
