Hi osmenaornela92,
Thanks for reaching to us.
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. Go to Dashboard -> Updates and click on Check Again.
5. Try to update the theme via Appearance -> Themes or via Dashboard -> Updates.
I highly recommend you to take a complete backup of your site before proceeding.
Or create a devsite – also called a Staging platform where you can test issues, enable/disable features/plugins thus such changes will affect the main site. The below article will help you to create it:
