I am trying to register my valid license. I always get the error: “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.”
We are not using the license on any other website.
It might be the issue of plugin conflict, cache issue or any browser extension that is not allowing you to validate your theme. I would suggest you troubleshoot with a few of the common issues before we investigate your settings.
