Please i use hot joomla for my site.
I upgraded to the latest version and since then my product details does not show again.
When users on the web click the product it gives this message

Fatal error: Call to undefined method shopFunctionsF::PdfIcon() in /home/afrishoc/public_html/templates/hot_ecommerce/html/com_virtuemart/productdetails/default.php on line 77

PDF support is no longer in new version. You can comment that line , of delete it.
