I am using this Mod for usergroup colors

http://mods.mybboard.net/view/username-style

This changes the Group color in Forum but not in the post.

How to change that.

Can you explain a liitle bit of more , what you wanna say ?

I want to change usergroup color in post also. This Mod didnt do this.

Do you mean Username colour ?

This is most likely because your theme is heavily modified, I would contact the theme author and ask them about it. A board URL might help as well.
