Could not find matching close tag for "<%="

When I'm trying to set the POST method in the new.ejs, I keep getting the error 

"Could not find matching close tag for "<%="."

Even when I try copy and pasting his code just to find out where the syntax went wrong, it gives me the exact same error. I changed the name from _form_fields to form_fields instead.

<%- include('form_fields.ejs') %>
