Background of the issue:
The website versteckter Link was previously managed by another business entity. We have now moved the management in-house. We encountered an error related to the site key and are trying to update it to a new one. The documentation mentions a 'Registration' section under 'Support', but this option is not visible in our installation.
Symptoms:
Error in the log: 'wpml: Unable to register: Site key not matching'.
Questions:
Where can I change the site key in WPML?
Why is the 'Registration' section under 'Support' not appearing in our installation?
