Problem:
When attempting to translate the website http://www.confobird.es into different domains with WPML (www.confobird.fr for French and http://www.confobird.uk for English), the domains appear as "Not Valid" in the plugin, despite being parked in the hosting. After configuring, the translated pages show a long URL starting with "https://confobird.fr/?xdomain_data=...".
Solution:
1. For the "Not Valid" issue, try saving the configuration without selecting the option to validate domains. Create a test page, translate it, and check if it appears correctly in all languages. If it does, it may be a false positive. If not, contact your hosting provider to verify the configuration of secondary domains.
2. To remove the "?xdomain_data=..." from the URL, go to WPML -> Languages -> Language URL format -> Select the option to pass user (or authentication) data via 'post' (change from 'get' if selected) -> Save changes and update permalinks.
