i went from an advanced layout to a simple layout (a premade background) and now I cannot change the post text background color.

Is there something I can do to change the color of this field? Currently my forums cannot be viewed because of the color not changing and the text being too similar in color. Hard on the eyes =(

Check out the colors set per rank in Admin > Ranks. If it didn't change, it sounds like you had colors set up on the Ranks.

What's the address of your site?

Hi chops.

its immortalsguild.dkpsystem.com

Alrighty, I'm assuming you're not the top Administrator. You'll want to have him/her modify the post colors defined in the Ranks. The best approach is to clear them altogether, and only change ones with special significance (like the Blizzard Blue Posts) or even my dark red color here to signify the "Official Response"
