work fine on 4.2, only doing the first 2 steps.
Open pages.php
FIND:
Code:
# Assign the current location line
$smarty->assign("location", $location);
BEFORE ADD:
Code:
if ($active_modules["Bestsellers"])
include $xcart_dir."/modules/Bestsellers/bestsellers.php";
no need for anything else on 4.2 try it on 4.3 versions.Always take backup of your original files.
Thanks
