Thanks for writing in! I have checked your licenses, and I see that you don't have any valid site URL assigned to your licenses.
Instead of site name, you need to assign your site URL (
example.com) and then you should be able to validate your site. You can also check our product validation guide here (https://theme.co/apex/forum/t/setup-product-validation/55).
If you're still having issues, please provide us with your WordPress login credentials in a secure note to check your issue further.
