sh404sef and Virtuemart pagination issue

Insert this in component/com_sh404sef/sef_ext/com_virtuemart.php just after the function definitions (eg: if (!function_exists('vmSefGetProductName')) i.e. at around line 95):

In backend settings:

Look for Virtuemart configuration in plugins page
- Select to YES the option that says “Using Items per page drop-down list”
- Save your settings
- Purge SEF urls
