I'm sorry to hear that you're having difficulty. Unfortunately from the information you have provided, I cannot say for certain why you are being asked to validate the site. I can see that in your licenses page here with us, the URL assigned begins with
http:// whereas the site itself is secured and begins with
https://. This could be the reason for the issue, so I would suggest you test this by updating the URL in your licenses page and seeing if that resolves the problem.
If it does not, check that the license code on your licenses page matches exactly the license code in your WordPress dashboard under X > Overview.
You can see more about validation in this knowledge base article:
If after going through everything outlined above you are unable to resolve this, please let us know and provide us with login credentials (login url, username and password) to your site in a secure note (click the key icon beneath your post to add this), and we will take a closer look at your setup.
Either way, let us know how you get on. Thanks!
