Dear support,
We have purchased your theme but somehow the api key isnt set anymore. So we added the license key from our account on your site but then we get the [Could not establish connection. Please ensure your firewall is not blocking requests to theme.co] message (had contact with hosting and there is no firewall blocking it). Whats wrong?
