Hello,
Our old header settings were deprecated 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. You just need to change colors, logo image 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/
Also you can simply import the headers if you want. From the WoodMart >> Header Builder >> Import as in the screenshot: https://jmp.sh/2m7Csta
After clicking import option you have to paste the json file code in the box and hit the Import button. https://jmp.sh/Cl44C1C
You will find the header json file from wp-content\themes\woodmart\inc\dummy-content\demoName >> header-1.json. Just open the file and copy the code and paste it as I described above.
Best Regards.
