Comments Section Broken

I run the site https://stylepointsblog.com/ and the comments have plum stopped working. We just realized it yesterday. We installed WP Super Cache, and that’s the only HTML thing we’ve done lately. Please please help, I’m flustered and confused.

We get a search page when we try and comment.
