[Plugin: Control Facebook Like Box by Beyond 5280] PHP Array code displaying on page

After installing I added the widget and inserted my FB page url and CSS class. It displayed the Like Box but above the box was some PHP Array code. Didn’t bother to look at it further, since I expect I widget like this to work out of the box.
