Hi,
I don't see how this is linked to the update.
The problem is with your custom CSS which is not correct.
You've added that CSS:
.hikashop_product_left_part {
width: 70% !important;
}
But it should actually be:
.hikashop_product_left_part {
width: 100% !important;
}
#hikashop_main_image_div{
width: 70% !important;
}
Doing that change, I actually get that display which looks fine to me:
