Facebook Link in widget broken

[Direct Webstore]

All the links to social networks are prefixed by "//" (e.g //www. facebook......etc). This is OK for all the other social network links but not the Facebook one in the ICONOSQUARE widget. See pic.

If I remove the "//" ... the Facebook link in the widget works, but none of the other Facebook links/icons work.
With the // removed, the other links/icons have an URL like "www.mysite.com/www.facebook.com"

???

Nevermind. Reinstalled my theme, then made a child theme and the problem disapeared. I must have deleted something by accident.
