This thread is resolved. Here is a description of the problem and solution.
Problem:
After updating the site, the contact form stopped working, and the English version of the contact page displayed Swedish content. Additionally, a 503 Service Unavailable error appeared, suggesting a server-related issue.
Solution:
First, we recommend checking if the contact form works when temporarily deactivating the WPML plugins. If the issue persists, it might be related to caching or a security plugin blocking the request. Furthermore, ensure you are using the WPML Multilingual for CF7 plugin to maintain compatibility between WPML and Contact Form 7. You can find more information and installation instructions here: Using Contact Form 7 with WPML. Always back up your database before making any changes.
If this solution does not resolve your issue or seems outdated, please check the related known issues, verify the version of the permanent fix, and confirm that you have installed the latest versions of themes and plugins. If necessary, do not hesitate to open a new support ticket for further assistance at WPML support forum.
