The copyright section text needs a change of color. I mean it looks off and there may be an SEO penalty. Google will penalize if its the same color as the background. Not sure how close they match colors but its certainly hard to read on he average monitor. Some people might take it in bad faith.
Chances are it occurred because of the common color used for text on the content pages. Just need to check the style properties to see if that area can be adjusted individually or it will just need to be done in the CSS instead if not.
