Fluent Forms - Error messages from Global settings are not translatable

Overview of the issue

When using Fluent Forms with WPML, custom error messages added directly to individual forms are translatable via the Advanced Translation Editor, but default messages from Fluent Forms’ global settings (e.g., «This field is required.») are not available for translation.

Workaround

• Go to WPML > Settings > Custom XML Configuration in your WordPress dashboard.
• Add the following XML configuration and save:

  <wpml-config>
    <admin-texts>
      <key name="_fluentform_global_form_settings">
        <key name="default_messages">
          <key name="*"/>
        </key>
      </key>
    </admin-texts>
  </wpml-config>
          

• Go to WPML > String Translation to translate the global error messages.
