UBB.threads PHP Forum Software Community Forums Resources and Customizing How Do I? Can't define styles of shoutbox!

Unfortunately it is not

See http://www.fabulaemarrii.com/ubbthreads7/ubbthreads.php

My problem is that in the white bars of the shoutbox, all links have a grey background. I want to change this into white.

In the link sections of rightalt1, rightalt2, alt1 and alt2, "color" is equal to "background" - so these cannot be the problem.

So what is?!
