A few hours ago, version 1.2.6 of WP User Manager was released. This update includes a series of bug fixes. An annoying bug regarding registration fields such as the username or the email field, has been fixed too. The fix however needs to be manually applied. Please head over to “Users -> WPUM Settings -> Tool” and press the “Restore Fields” button. This will fix the fields that had disappeared from the registration form.
Stay tuned for more updates.
