I've been reading for HOURS looking for an answer to this. I have done EVERYTHING EXACTLY like the examples. Which are not consistent. In some places it shows the URL without the http://www. and other times it shows it with it. I typed mine exactly as it showed in the examples and it didn't work.
So I went back and made ALL of the domains the same
http://www.mydomain.com and went through it all again.
THIS time I get this error when trying to post to FaceBook:
(#200) The user hasn't authorized the application to perform this action
Why is this so hard? So many people have the same issue. Everyone seems to have to provide their login information to have someone else help them. Maybe that's what I'll have to do too.
Please help.
