Hello,
2) I do not see any translation for Core plugin on your site http://prntscr.com/pxpniu
3) Create images folder into your child theme and upload images there + add the next custom CSS code in style.css of your child theme:
.fixed-header .menu > li.badge-new > a:before,
.main-nav .menu > li.badge-new > a:before {
background-image: url(wp-content/themes/legenda-child/images/new-icon.png);
}
.fixed-header .menu > li.badge-hot > a:before,
.main-nav .menu > li.badge-hot > a:before {
background-image: url(wp-content/themes/legenda-child/images/hot-icon.png);
}
.fixed-header .menu > li.badge-sale > a:before,
.main-nav .menu > li.badge-sale > a:before {
background-image: url(wp-content/themes/legenda-child/images/sale-icon.png);
}
.fixed-header .menu > li .nav-sublist-dropdown ul li.badge-new > a:after,
.main-nav .menu > li .nav-sublist-dropdown ul li.badge-new > a:after {
background-image: url(wp-content/themes/legenda-child/images/new-icon.png);
}
.fixed-header .menu > li .nav-sublist-dropdown ul li.badge-hot > a:after,
.main-nav .menu > li .nav-sublist-dropdown ul li.badge-hot > a:after {
background-image: url(wp-content/themes/legenda-child/images/hot-icon.png);
}
.fixed-header .menu > li .nav-sublist-dropdown ul li.badge-sale > a:after,
.main-nav .menu > li .nav-sublist-dropdown ul li.badge-sale > a:after {
background-image: url(wp-content/themes/legenda-child/images/sale-icon.png);
}
.menu ul > li.badge-new > a:after {
background-image: url(wp-content/themes/legenda-child/images/new-icon.png);
}
.menu ul > li.badge-sale > a:after {
background-image: url(wp-content/themes/legenda-child/images/sale-icon.png);
}
.menu ul > li.badge-hot > a:after {
background-image: url(wp-content/themes/legenda-child/images/hot-icon.png);
}
