Hello,
I have found that you are using the oldest version of the theme. Please update the theme to the latest WoodMart 4.5.2 and update all the theme plugins as well. I am sure after the theme and plugin update your issue will be solved.
Please follow the steps:
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 still you need help then share your FTP Login details so I’ll update the Theme for you.
Best Regards.
