Hi
I’m running WordPress 5.7 on MultiSite. Everything was working fine until upgrading X from 7.x to 8.3. After That it asked for Conerstone to be update from 4.x to 5.x. But Cornerstone cannot be updated without a valid license.
Trying to activate the license always gives the same error, even after removing an assignment of a license.
The message is:
" 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."
Doing so doesn’t help at all. Out of any hope, I’ve converted X to PRO. But activation fails, still.
Please assist.
Kind regards
Stefan
