(before this I wrote something about the base_tag, please ignore it ...)
I don't know why, but when I load my site through the silverstripe template-engine, the body-background ends, when the last div ends. The error also occurs without anything changed in the template (like base_tag %meta_tags, %Content ...). When I load the template directly from hd (...index.html) everything is fine.
This problem only occours in firefox, in IE6 or opera everything is fine.
