In case anyone has the same issue, it was resolved by entering this piece of code into CSS Styles under Theme Options:
#featured-image {
display:none;
}
.col-460 {
width: 100%;
}
They contacted me directly by email, rather than responding via a post. Sorry, I don’t know what their forum account is. Thanks for responding!
Update: I was able to remove the chimp graphic, but I’m still unable to restore the text width to full page. This is the Responsive Theme. Any help would be much appreciated. Thanks!
