You are experiencing issues with form submissions using WPForms on a multilingual WordPress site when WPML and WPML String Translation are activated. The forms fail to submit under these conditions.
Solution:
First, ensure you back up your site. Then, perform the following steps to diagnose and potentially resolve the issue:
1. Temporarily switch to a default WordPress theme, such as 2023 or 2024. 2. Deactivate all plugins not related to WPML, except for the WPForms plugin. 3. Check if the form submission issue persists. 4. If the issue is resolved, reactivate your other plugins in groups of three or four to identify any that may be causing a conflict. 5. Finally, revert to your original theme.
Additionally, ensure that your WordPress, WPML, and all other plugins and themes are updated to their latest versions, as recent updates include fixes for similar issues.
If these steps do not resolve the issue or if the solution seems outdated or irrelevant to your specific case, we recommend opening a new support ticket. We also 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.
