Problem:
The client is experiencing a 500 Internal Server Error when accessing translated versions of their website in languages other than the main language (Spanish). This issue occurs specifically with URLs like /nl/, /fr/, /de/, etc. The error does not affect the default Spanish pages. The problem seems to be related to the Homelengo Real Estate theme, which triggers a PHP fatal error when WPML is active or when visiting pages in secondary languages. Additionally, there are issues with internal redirects and REST endpoints used by Contact Form 7.

Solution:
We recommend the following steps to troubleshoot and potentially resolve the issue:
1. Contact the hosting provider to check the server error logs for more specific details about the error.
2. Disable the Homelengo Real Estate theme temporarily to see if the issue persists with a default theme.
3. Deactivate and reactivate WPML and Contact Form 7 to check if the issue is specifically related to these plugins.
4. Review and possibly adjust the .htaccess file to normalize /wp-json with language prefixes.
5. Flush permalinks and caches to ensure no stale settings are causing the issue.
6. If the problem continues, provide the debug log to the WPML support team for further analysis. You can find instructions on how to provide this information here: https://wpml.org/faq/provide-debug-information-faster-support/

If these steps do not resolve the issue or if the solution seems outdated or irrelevant to your specific case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If problems persist, please open a new support ticket with us for further assistance.
