I'm adjusting an existing theme called Tweaker4.
I have changed the menu bar to go ontop of the header image. Unfortunatly the sub menus stay hidden behind the header.
I have tried changing the z-index and overflow:hidden But no success.
Here's a link to the page : http://www.shiatsuprovence.com/wp/la-seance/
It's the second link from the left "la séance".
Any help would be appreciated.
