Contact details in header

I forgot how I added my contact details in Header.php.
Pls let me know which file consists Social Icons in Header , it is NOT header.php, Style , etc.Tried through Inspect element.
Problem : 2 images of FB & G+ path now not reachable , shows blank,only Twitter is working,

Hello there,

I hope you are doing well today.

  1. You would have edited the header extensions file via library/structure/header-extensions.php.
    2.The code you added may have affected the images but Google+ is being discontinued so you may not need to use that.

Best Regards,
