Hi
Before HikaShop 4.4.2, we were not using font awesome for these icons but simple images. In order to simplify customization and make it more consistent with the rest of the interface of HikaShop, which already uses font awesome everywhere else, we changed these buttons to migrate to font awesome.
The issue you have with the updated page comes from the custom CSS of your template. Your template adds special CSS to customize these buttons using its font awesome and hid the image HikaShop was using.
It's done with the code:
.hikashop_product_page .hikashop_next_product, .hikashop_product_page .hikashop_previous_product { background: none; position: absolute; z-index: 2; right: -15px; top: 10px; color: #FF9900; font-size: 1.5em; }
.hikashop_product_page .hikashop_next_product:hover, .hikashop_product_page .hikashop_previous_product:hover { color: #D1BD98; }
.hikashop_product_page .hikashop_next_product:before, .hikashop_product_page .hikashop_previous_product:before { font-family: "FontAwesome"; content: "\f054"; }
.hikashop_product_page .hikashop_previous_product { right: 10px; }
.hikashop_product_page .hikashop_previous_product:before { content: "\f053"; }
in the file /templates/ignite/css/template.css
So remove the lines:
.hikashop_product_page .hikashop_next_product:before, .hikashop_product_page .hikashop_previous_product:before { font-family: "FontAwesome"; content: "\f054"; }
and
.hikashop_product_page .hikashop_previous_product:before { content: "\f053"; }
and add instead the code:
.hikashop_previous_product_btn p, .hikashop_next_product_btn p {
display: none;
}
.hikashop_previous_product_btn, .hikashop_next_product_btn {
border: 0;
}
from there and it will look close to what you had before.
I would recommend reporting the issue to your template provider so that they can update the CSS in their template.
