To avoid misunderstandings.
For WB 2.10 and WB 2.11 use the exact same template.
In WB 2.10 the Topslider appears when opening page.
In WB 2.11 the Headerpicture appears when opening page.
In WB 2.11 I want the slider to start when I open the page, then I have to swap the Topslider rule with the Headerpicture rule in the template.
After exchanging the rules, it works perfectly.
But in my opinion this should not be necessary with a template that has not changed anything.
