Hi,
That's strange, I can see that you indeed did the install of the 4.4.2 with the patch (since the build number in the "version" displayed on the HikaShop configuration has been properly incremented), but you still don't have the change in the file media/com_hikashop/js/hikashop.js like I can see in the file of the install package.
It's as if Joomla didn't overwrite the file with the new version because of a permission issue on the file.
So let's do it differently.
Replace the code:
for(var i = 0; i < scriptsAlreadyLoaded.length; i++)
if(scriptsAlreadyLoaded[i].getAttribute('src').includes(result[1]))
return '';
to:
for(var i = 0; i < scriptsAlreadyLoaded.length; i++) {
var src = scriptsAlreadyLoaded[i].getAttribute('src');
if(src && src.includes(result[1]))
return '';
}
in the file media/com_hikashop/js/hikashop.js
Then, clear your browser's cache and it should then work properly.
