I try to change my website domain and redo my site. I reasigned my new url under my validation code and enter the code to my x. However, the system is always saying that “Your code is valid but looks like it has already been used on another site. You can revoke and re-assign within your Themeco account.” Are there anything I missed?
If your old domain is still active then make sure to revoke the validation from X Addons menu. Then try removing all domains from the license and add new one again.
