Problem: The client is trying to translate a form and its email notifications using WPForms with WPML Core, String Translation, and WPForms Multilingual.
Solution: 1. We asked the client to upload the WPForms plugin to a clean test WordPress install provided by us to check for compatibility issues. We emphasized that only the plugin and related functionality were needed, not the entire website. https://wpml.org/faq/how-to-reproduce-issues-and-share-them-with-wpml-support/
3. We clarified that it is not possible to activate ATE specifically for form translation, but the client can temporarily activate it in WPML → Settings → Translation Editor.
If the solution provided here is not relevant to your case, either because it's outdated or it doesn't apply to your situation, we recommend opening a new support ticket.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.
