Problem: If you're trying to update WPML modules such as WPML Media, WPML Multilingual CMS, and WPML String Translation, but encounter an error stating 'WPML Multilingual CMS cannot update because your site's registration is not valid. Please register WPML again for this site first.', follow the steps below. Solution: 1. Verify your WPML key and the domain used for that key on your WPML account page. 2. Provide temporary access to your site (wp-admin and FTP) to the WPML support team, ensuring you have a full backup of your site before doing so. For privacy and security policy, refer to this link. 3. After providing access, the WPML support team will attempt to register WPML using the key you provided and check for updates. 4. If successful, WPML and its add-ons will be updated to the latest version. 5. If you see a notice stating 'WPML plugin cannot connect to wpml.org', it may be a false positive due to local or server caching and should resolve itself when the cache clears.
