In my package NeosRulez.Bootstrap I have a Bootstrap container NodeType. In Neos 3, inserting elements into this NodeType works fine. But in Neos 4 I can insert content elements in the container NodeType, they are not visible on the page and they are not editable.
The frame in which content elements can be inserted in a ContentCollection is also not visible. I’ve already disabled stylesheets because I thought it might be because of that.
When I disable the NeosRulez.Bootstrap package everything works fine.
This is my package: https://github.com/patriceckhart/NeosRulez.Bootstrap
Can someone help me?
