I have purchased the OneLander theme, but some icons appear as boxes, everything seems to be setup ok and I checked a few threads here as one of the more obvious places where boxes are displaying in place of icons is on the top menu (social icons).

I haven't installed any other 3rd party plugins as yet. I can PM the site details, but perhaps there is a quick fix?
