I am trying to configure name badges for CiviEvent events.
When trying to configure the pictures, for upper left/right corner, an unformatted page opens and clicking on links like upload returns an error.
Any hint how to fix this? I checked civicrm.settings.php to ensure that the correct path is used and that the permissions for the upload folder are correct.
Any other way to get the pictures up and placed on the right place?
CiviCRM 5.8.1 Wordpress 5.0.2
