We’ve just encountered what seems to be a bug. We’re using WPML to translate our sites from English to French, and were recently working on our headers and footers using the Pro editor.
We found an issue where one of our translators added in the translated version of the header/footer, set the viewing conditions and saved them, however on the front end the translated headers and footers did not appear. Upon refreshing the editor, none of the changes were saved, and the French side of the header and footer had been cleared out. This issue doesn’t happen with translating pages using the Pro editor, just the headers and footers, and took place on several of our sites.
Upon further investigation, we had someone with super admin access (all our other translators had admin access, just not super admin privileges) add the translation to the headers and footers, which saved, appeared on the frontend, and could be accessed from the Pro editor again. However, once saved, if another of the translators went in and edited them and saved their changes, they would once again disappear from the frontend and would be blank the next time they were accessed from the Pro editor. Providing these translators with super admin privileges now allows them to add the translations using the Pro editor without any issues, so it appears that there may be an issue with permissions that allows admins to access the headers and footers through the Pro editor, but saving them causes it to become blank unless you’re also a super admin.
