edegree theme

having a couple issues with this new theme. first, the featured plugin is giving me some difficulties. i went to themes > homepage and just clicked that box that says i don’t want to use it, but now i have an unsightly black bar on the top of my screen.

next, i have some icons on my page for facebook, twitter, youtube, and one that i’m not sure of. i have a twitter and facebook account that i would like to put the url here, but not sure how.

thanks.
