Social icons not showing – SOLVED:
I went to Appearance -> Widgets and removed ALL widgets from Header (moved them under Inactive Widgets) and the social icons appeared!
@arsenico: now it looks like in you example link
@staud: try this, should solve your problem
@annettesaunders17: follow the above and enter your social links under Theme Options
Only problem now is that the Full Width layout option does not work, it only shows narrow width – any ideas?
