Hi. I created my wordpress site using a temporary URL and X | The Theme. I did not register it however, now that I have switched to the permanent URL and tried to register so that I can have the automatic updates begin, it says “Sorry, but it looks like that purchase code has already been registered with another account.” which it hasn’t.
Based on the information that you’ve shared, I assumed that you have assigned your license to your temporary url and now you want to validated your permanent url. Please login to your account here: https://community.theme.co/users/chanarae/licenses/ and revoke the license. You need to reassign it to your new and permanent url.
