I am trying to activate X but it comes up with the error “Uh ohm we couldn’t check if this licenses was valid”.
I tried everything in the forum – checking the domain name and upgrading Cornerstone – but it is still a problem.
This was a code I used on a previous web site (for 2017) and I am trying to move it to a 2018 version. I did deactivate it on the old site.
