Problem: The client is experiencing an issue where the 'en-eu' hreflang tag is missing, and an incorrect 'en-nl' hreflang tag is appearing on their technical SEO page, even though they do not have a Dutch (nl) language set up on their website. Solution: 1. Confirm that the 'en-us' translation page exists and is correctly linked. Also, ensure that 'x-default' correctly points to the default language page. 2. Perform a backup of your site. 3. Disable all plugins except for WPML plugins and switch to the WordPress default theme to check if the issue persists. 4. If the problem continues under these minimal conditions, provide wp-admin access for further investigation. 5. It was discovered that the 'en-nl' hreflang was incorrectly set for Basque language in the WPML language settings. Correcting this setting should resolve the issue.
