Hello,
"next / prev arrows in the products display"
You will find this option to shutdown prev/next button in your Main HikaShop Configuration :
"
hide the Thumbnails slider in the products display"
We have just look your website and it seems that you don't use any hikashop frontend file css (or you only use a custom version of this frontend).
That's why some css commabnd are missing to manage this new feature.
From this 2 solutions for you :
1. You analyze the frontend css file of the HikaShop
4.4.2 to add required
Css command to link options with this display feature
OR
2. You want shutdown this option, and you can just add this command :
a.hikashop_slide_next,
a.hikashop_slide_prev {
display: none;
}
Note : To see how to add custom command to your frontend file css, see this
documentation
.
Hope this will help you to correct your issue.
Regards
