This one caused me fits as well, so I coughed up some points to get it resolved.
1. Add a new static page (embedded level) with the following code, put it where you want the items to show.
Code:
{ include file="modules/Bestsellers/bestsellers.tpl" }
2. Add to the
<xcart_dir>/pages.php as shown below:
Code:
if ($pageid == <page_id>)
include $xcart_dir."/modules/Bestsellers/bestsellers.php";
where you should replace <page_id> with the page id of the static page created at step one.
You can pretty much do this for any of the modules, not just bestsellers!
