I Can't See Menu Configuration after update

[Fever]

Hello everybody!
First Of All forgive my english. I Know it's not very good so I hope you can understand me anyway.
I've updated my gallery to 1.5.8 and after the upgrade the configuration menu is gone! I can also see pictures only in administrator mode

you can see my gallery here www.gagatribe.com/gallery
