mbctkim1 on "Error 500 - Internal Server Error"

So I am hosting through Hub and I went to cPanel and looked at my error log. It doesn't list anything.

When I click on the option for Edit Error Pages is says:

Editing 500.shtml (Internal server error)
You are editing the error pages for the domain craftimess.com.

Select Tags to Insert: choices are
referring URL
visitors IP addres
requested URL
server name
visitor's browser
redirect status code

I'm obviously very confused. Thanks in advance for your help and patience.
