I have a functional web site in J2.5 VM 2.6 at http://palazzetti.ca using the gk_esport template>
I have created a new site and installed Storefront in J2.5 VM 2.6, as a first step to migrate in the future to J3 VM3.
I turned on VM Debug on the new site http://2015.palazzetti.ca
When I try to display a VM product page I get the following error:
Fatal error: Call to undefined method shopFunctionsF::renderVmSubLayout() in /var/www/vhosts/palazzetti.ca/2015.palazzetti.ca/templates/gk_storefront/html/com_virtuemart/productdetails/default.php on line 28
Suggestions?
