Hello,
I moved the domain name from dev to production name, behind bunnycdn.
I tried to change/reactivate the licence on the right name, but I now have:

“License key is correct but already in use on another site. See the FAQ for how to enable Pro version in development mode.”

I searched the FAQ, but I did not fuind anything.
I tried to save with no licence key (empty box), but no more success.

Now the site is in production, i can not revert back to dev name to unset the licence.

Can you help me ?
Thank you.
