Foobox + WP super cache

Hi,

I have a bug when I open a foogallery image with foobox.

Once the image is opened, the next and previous logos change shape. To be replaced by a linux logo and a triangle.

After searching, I found it’s wordpress super cache that causes the bug. I have black list, page, plugin foobox, foogallery plugin … but impossible to have a return to normal with the logos arrows.

Do you have a workaround?
