Forum Color setting why isn't it working? I try to set ex. "support forum" green, but no change.
If you scroll down the Color Setting page you'll see all information why it may not work and how to fix. In most cases it's cache issue. You have cache plugin. You should delete all caches, then navigate to forum front-end and press Ctrl+F5 twice to reset/delete browser cache as well. If you still don't see the color cache then follow to to instruction below that admin page.
