Stuff really changes fast on Facebook. I had an email from
one of my subscribers telling me that a few of the fields
on the apps page had changed.
Here’s the body of the email with my answers. Should be
clear, but if you have any questions, just reply to this
email.
Hope you’re having an awesome weekend! 
The email is below my name.

Q: Hi Lee, in the cheatsheet section 3 of the PDf where it
says “Creating The App” and is numbered 1 through 10, I
noticed there is an extra field (App Domain) on my page
that is not on your page in the PDF. I don’t know what
to enter in that field becausi I don’t want to get any
part of this wrong. Should I just put my domain root
(e.g. mydomain.com), or the complete domain path if
there is a sub-folder or a sub-domain?
A: Just put your domain with the extension in there.
So, if it’s http://www.yourdomainname.com, you’ll put
“yourdomainame.com” into that field.
Q: Also, in the same cheatsheet section 3 area where it
says “App on Facebook”. there are only 2 fields on my page
(“Canvas URL”, and “Secure Canvas URL”) but there are 3
fields on your page in the PDF (Canvas URL”,”Secure Canvas
URL and “Canvas Page”. What should I enter in the “Canvas
Page” field?
A: Just fill in the ones you see.
