How can I fix this

[theparentpack]

I am creating a new custom style. For some reason I am seeing a black background with dark text in a couple of places where there should be my custom Orange background, like the footer and a few other places with subforums.

Also, I noticed that my username is invisible against the black background in posts, as well as below the What's Going On? strip at the bottom of the forums. I am the only Admin, and everyone elses username is white. I am attaching screenshots. How can I fix these issues? I have been playing around with the style and have yet to find a way to correct any of these issues.
