Hi,
Don’t know whether you’d still like an answer, but I had the same problem. I solved this problem liks this: I don’t, for example, have Instagram, so I replaced the Instagram button for the Pinterest button in the editor. To do that, you go to the editor and then to social-buttons.php. Where it says: original-title=”Instagram” you replace the word Instagram for the word Pinterest. Where it says fa fa-instagram, you also replace the word instagram for the word pinterest (don’t change id=instagram though). This way the Instagram button will be replaced by a Pinterest button and when you hover over it, it will say Pinterest rather than Instagram. Then you go to theme options -> social media links and you insert your Pinterest url where it says ‘insert your Instagram url’.
If you do have Instagram, but not for example LinkedIn, then you can do the same thing, only you change the word ‘LinkedIn’ for Pinterest rather than replacing the word Instagram.
Hope this helps. It worked for me!
