In my account license dashboard, I have set up a staging web site URL.
I then downloaded the PRO theme, uploaded it to my staging web site, activated it, and tried to enter the license but the message said:
"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."
This cannot be possible, this is the very first time, that I have ever made use of a staging web site. Please help.
