Hello,

Try to do the following to update the theme:

1. Go to Dashboard -> WoodMart -> Theme License and deactivate the theme.

2. Go to Dashboard -> Updates and click on Check Again.

3. Activate the theme with your purchase code again.

4. Try to update the theme via Appearance -> Themes or via Dashboard -> Updates.

If it does not help, make the full backup of your site and update via FTP https://xtemos.com/docs/woodmart/update-theme-2/

If you need help, provide FTP access to the private area.

Best Regards
