1. License is not activated
As you may know, all our themes support automatic updates, but sometimes you may see this error “Download link could not be retrieved” when trying to update the theme.
In most cases the solution is simple – you just have to activate the theme license. Learn more here – https://nkdev.info/docs/wordpress-themes-basic/theme-license/
Once the license is activated, try to update the theme again.
2. Site domain name changed
If you changed your site domain name – switched from the staging site or migrated to the new domain, you will need to reactivate your license key. Learn here how to manage licenses – https://nkdev.info/docs/wordpress-themes-basic/theme-license/#manage-active-sites
The same error may occur if you try to update premium plugins. How to update bundled premium plugins, learn here – https://nkdev.info/docs/wordpress-themes-basic/premium-plugins-update/
