In WordPress 4.9.6, new tools were added to make compliance easier with laws like the European Union’s General Data Protection Regulation, or GDPR for short. To assist our users this plugin also hook to those tools to make it easier to export and erase messages and announcements.
As an admin of your website you have full control of that. So we added a new settings tab called “Privacy” under Front End PM > Settings. You can set what information will be exported or erased when a data export or erase request is made and completed.
