Original display diazo theme

Hello all ! I've got a little question: I had a Diazo theme installed (booster), and it was good looking (with the big image on the homepage). I missclicked on the display button and changed the site display. Since that, I can't get my homepage back to her original look... How to do that?

Set display to the content item 'Front Page'

I deleted accidentally the homepage, how coul I bring her back?

Try the Zope Undo form on the Plone site root, or Zope root (ie, localhost:8080/Plone/manage_UndoForm or localhost:8080/manage_UndoForm).

Look for something like 'POST localhos:8080/Plone/front-page/delete_confirmation' and undo that transaction.
