Hi,
First please follow Ismael's instructions above.
Do you mean the orange outline? Take a look in your backend > Sentence > Styling > Background Image (Label: This background image of your site). It should be a dropdown select menu of colors, make sure you chose '----------------------'. The font causing that orange color is ff8c00, and on the same page look at the other options which show color codes if you can spot it.
You are also pulling some stuff out of blog.riveroaks.org which may be partially responsible for the orange color. Hard to tell. This line in your header is throwing an error since you are telling the theme to load javascript while its not finding any javascript at that url.
