I am literally crying right now please someone help me

I have been trying to get this plugin to work for two days. Im literally crying right now trying to figure out what I am doing wrong. I created an app…apparently my app detail page is being reviewed for approval??? none of the features work, it isnt posting to my page.
All the guides make it look easy, but when I tried to follow the directions, I was directed through alot of extra steps such as uploading screenshots, creating privacy pages…..all to no avail. I wan tthe comments box below posts, I want to be able to automatically post to website facebook page….
My website is at illquotes.ridquest.com

Thanks in advance
