Hi hey3212,
Thanks for reaching to us.
First of all, I’m really sorry have taken long time to reply you due to the weekend.
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:
