Thank you @ ruenel for your reply, but even after I followed your steps, it still won’t validate. Can you please assist. I need to update X and Cornerstone for my client’s site. I can manually update X by uploading the new version, however, Cornerstone still won’t update. Plus, I’d like the license to be validated, since it had been and should still be.
