I registered my Avada theme license on a local server. I migrated to my ovh server and now the license is no longer valid. I must tell you that usernames and passwords are the same. Only the identifier on themeforest is different, since I did register through google, but I have several addresses linked to it. Could you please help me as I am now stuck.
To use purchase code (license) again which already used for any website (mean theme license already registered) you have to unregister/deactivate the theme license from the local server. you can not use the same purchase code 2 times when previous one is active. So, you can deregister the license from the local server then try to use the license in your main server.
contact the theme Author and let them know How to Contact your purchased theme Author, the theme author will be happy to assist you within their scope.
