Hello,
Thanks for your link, first point I note that your Css class li aren't as expected.
For be more specific, HikaShop since 3 version use his own grid system to manage display, and for the frontend_default.css use specific class, as you can see it on this screenshot :
On your side we have this :
I think that you have an
override on listing_list view, and that explain why your HikaShop use an old view version despite the update and so, don't have the
grid-system class.
Can you via
ftp, try to change your
listing_list file name (for by example listing_list_2) in :
YourWebsite/templates/YourTemplate/html/com_hikashop/product/
That will "
switch off" the override view, and you will see if that solve your issue.
Regards
