I did some changes on my website and there seems to be a problem. While everything in the new theme is working, I found out that there is an annoying facebook icon, located on top of my header and top bar.

This is what it looks like:

I would like to know why there's a facebook icon there and how can I remove it? I am using a Basic Wordpress deal, so know that I can not actually go to the code and remove it.

Thank you!
