title: cant assign any modules to category layout in Opencart 2
body: <p>I have a Opencart 2.0.1.1 installed on my server with a few modules installed but I cant seem to assign them to the category layout.</p>
  
  <p>for an example, I have a banner and I have assigned it to the category layout but it doesnt show. But when I assign it to any information page or home page it shows.</p>
  
  <p>none of the a modules work for the category layout. There are no errors in the error log either</p>
  
  <p>Can someone let me know what might causing this problem and how can I fix it?</p>
