Redirecting to authentication dialog - “An error occurred. Please try again later”

Question

Why does it always happen to me?

This happens after my application verify for user user login and redirect user to the authentication page:

https://w

Answer 1

I was getting this error because I was starting from http://mysite.com, but had specified http://WWW.mysite.com in my Facebook settings - the www mattered... I ended up solving by using .httpaccess to always kill the "www", and pointing FB to http://mysite.com

worst. subdomain. ever. :u)
