The client is experiencing an error message 'Unable to register: Site key not matching' when attempting to register their site with WPML using a generated site key.
Solution:
1. Visit https://wpml.org/account/sites/ 2. If the site URL is already registered, delete it from the list. 3. Re-enter the site URL to generate a new site key. 4. Click on "Show key" and copy the new site key. 5. Navigate to Plugins > Install > Commercial (tab) and enter the new key to re-register WPML. If WPML is still registered, de-register it first.
