New behaviour: If left or right columns are empty, an empty placeholder will set with 1px height. That <div> affects, that the empty column will displayed in full width.

If you don't like this effect, please add this property to your CSS file:

.startVisHiddenHeight1 { display: none; }


If you have configured the TypoScript properties from below, YOU MUST update your configuration!

start.structure.content.left.20 is moved from CONTENT to COA
start.structure.content.right.20 is moved from CONTENT to COA
