Hello,
1. Please show a page where social icons are shown and specify if you want to change background color of the icons or color of icons themselves.
2. Please refer to this article:
https://www.8theme.com/blog/how-to-add-social-media-icons-to-wordpress-menus/
3. You can change breadcrumbs background in Theme Options > Color Scheme > Breadcrumbs background. If you want to set different background images for different pages then go to Pages > edit a page > upload image in “Background image for breadcrumbs” field in “Page Layout” box.
4. Add this code in Theme Options > Global Custom CSS:
.breadcrumbs span.current {
display: none;
}
5. You can use Woocommerce Layered Nav Filters widget in Appearance > Widgets and add it into “Shop Sidebar” area.
6. Sorry, but there is no such possibility.
7. Please show the issue on a screenshot and give us a direct link of the page.
8. Please refer to this article:
