unfortunally i´m not able to find out, why the Extra Fields are not displayed in my Easylayouts Templates for Blog Articles (Intro).
I´ve setup all fields in the Template as you can see here: https://www.screencast.com/t/djPzYh0wcUE
the problem is you set the field to be shown only to users with viewlevel: Onlineshop-2019 and only users in the user group called: Onlineshop-2019 are allowed to see items with that view level.
So either you make the custom field to allow Öffentlich view level, either your users need to be logged in to see the field
You can easily switch EasyLayouts off and on again via a special module on the demo site and can also access the backend to experiment with the layouts. The demo resets every hour so bear in mind that the demo looks a bit odd that someone else may have changed the layouts before you viewed the page.
