Responsive HTML Layout points to wrong page as the Home page where do I edit it?

Hi there

Not sure if this is what you are looking for, but right-click the Single Source Layout in the Single Source Layouts pod and choose Properties. Then click the Content category on the left and see what topic is nominated as the Default. If that's the topic you are presently seeing, click the Select... button and nominate the topic you wish to see.

Cheers... Rick
