Hi,
Q1)
It looks like your language file is only partially translated? Currently: 62%. Could you use POEdit and regenerate the files?
The translation does exist in the language file:
#: swift-framework/core/sf-header.php:1221
#: swift-framework/core/sf-woocommerce.php:615
#: swift-framework/core/sf-woocommerce.php:699
#, fuzzy
msgid "Your cart is empty."
msgstr "il tuo carrello"
#: swift-framework/core/sf-header.php:1270
#: swift-framework/core/sf-header.php:1272
msgid "View your wishlist"
msgstr "La tua wishlist"
Q2)
Your product pagination looks like that because you breadcrumb navigation is very long and overlaps it.
You could alter the top position of those with this CSS:
.summary-top .product-navigation {
top: 60px;
}
Thanks,
David.
