Hi,
1.
Do you have the social plugin from the system group enabled and configured properly ?
I don't see why it wouldn't work unless it's disabled or set to an access level preventing it from working its magic for public users.
2.
The CSS you're using comes from HikaShop 2.2.1 if you look here: media/com_hikashop/css/frontend_custom.css
You're missing all the CSS of the new tab system for the product page:
.hikashop_tabs_ul{
z-index: 2;
position: relative;
margin: 0px 0px 6px 0px;
}
.hikashop_tabs_ul li{
display: inline;
background-color: #fcfcfc;
padding: 8px 5px;
border: solid 1px #E7E7E7;
z-index: 2;
font-weight: bold;
}
.hikashop_tabs_ul li a{
color: #555555;
}
.hikashop_tabs_ul li a:hover{
text-decoration: none;
color: #555555;
}
.hikashop_tabs_content{
z-index: 1;
position: relative;
display: none;
min-height: 200px;
background-color: white;
border: solid 1px #E7E7E7;
padding: 5px;
-moz-border-radius-topright: 4px; -webkit-border-top-right-radius: 4px; -khtml-border-top-right-radius: 4px; border-top-right-radius: 4px;
-moz-border-radius-bottomright: 4px; -webkit-border-bottom-right-radius: 4px; -khtml-border-bottom-right-radius: 4px; border-bottom-right-radius: 4px;
-moz-border-radius-bottomleft: 4px; -webkit-border-bottom-left-radius: 4px; -khtml-border-bottom-left-radius: 4px; border-bottom-left-radius: 4px;
}
.hikashop_tabs_li_selected{
border-bottom: solid 1px #ffffff !important;
background-color: #ffffff !important;
}
.hikashop_tabs_li_selected a{
color: #1491B0 !important;
}
Add it and it should work better.
4. So what tax exactly do you want to turn off (can you provide a screenshot ?). What code were you trying to use ?
