Hi,
Our old header settings were deprecated since 2.0 version and we finally removed it to clear our theme from a lot of unnecessary code. So after the update, our header builder function is turned on so you need to configure a new header for your website. Actually, there is no much work there. As we can see, you just need to change colors, logo image, and top bar text in Dashboard -> WoodMart -> Header builder. You can find all the necessary tutorials and instructions for this in our documentation https://xtemos.com/docs/woodmart/header-builder/
Regards
