Problem: The client reported that a translated global form displayed correctly in various languages except English. In English, the form in the popup displayed in other languages, despite the footer form showing correctly in English. Solution: 1) We updated the translation of the header template in the default language, which resolved the issue with the popup form not displaying correctly. 2) The footer form was functioning correctly without any modifications. 3) We resolved the form translation issues through WPML-> String Translation.
