Hi There,
I saw a few syntax errors on your custom CSS (Theme Options > CSS) that needs to be addressed first because of it affecting other CSS blocks in that area including the last one that I provided.
First this block:
===============================================
/*woocommerce add to cart button display none
a.button.product_type_simple.add_to_cart_button.ajax_add_to_cart{
display:none;
}
a.button.product_type_variable.add_to_cart_button{
display:none !important;
}
form.cart{
display:none;
}
p.stock.in-stock{
display:none;
}
div.product_meta{
display:none;
}
p.woocommerce-result-count{
display:none;
}
select.orderby{
display:none;
}
p:empty {
display:none;
}*/
===============================================
Remove all the ===============================================
on that block as that is not a valid commenting, or you can remove that block all at once as you have commented that out.
Second, remove the extra #
on this block:
a.x-portfolio-filter {
color: ##512c1d;
}
Third, remove this block as this is an incomplete, no CSS property in it.
.option-set .x-portfolio-filters-menu>li>a:hover {none;
}
Hope it helps,
Cheers!
