Comments section gone

My posts are void of a comment section and I can’t figure out why. I tried all options in settings>discussions and can’t get it to pop up. Now my social sharing disappeared as well (not as important). What am I doing wrong? I use the same theme for http://dutchsoundsoff.com, and comments work fine. I have been looking through forums and testing ideas, but nothing is working. Please help.

Thanks, Dutch
