Since Page SP Page Builder Version 3.7.4 an additional entry for large monitors was added to the css files: @media (min-width: 1400px) {# view-overview> .sppb-row-container {max-width: 0px;} }. Why? Why should the container suddenly only be 0px wide, whereas on smaller screens it is a good 98% wide? Is that an error or why is the value set to 0px?
In the custom css file I now added the entry @media (min-width: 1400px) {# view-summary> .sppb-row-container {max-width: 1370px !Important; }} added. So that you can see the background-image.
