Help Needed with CSS Problem - Dark Elegant Theme

Hello everyone, I have been modding the Dark Elegant theme to suit the colors my husband wanted for his website and pretty much everything has been going fine except the theme goes odd when I hit the forums. I have scoured the style.css file from top to bottom and I cannot find out where I made the mistake that leaves the forums a light grey with black lettering instead of the dark grey with light blue lettering to match the rest of the site. I am about ready to pull my hair out over this one. Is there someone who is familiar with this theme that can tell me what CSS I would need to add to fix the background on the forum table? At this point I have no idea where it is even getting the light grey from because I have removed all light grey hex codes from Style.CSS.

Hi,

Do you mean something like this https://demo.drupalexp.com/7/jollyness/forum?

Thanks!
