Facebook API's fb:registration returning “Invalid 'client_id'” when not connected to Facebook

Question

I\'m trying to use Facebook\'s registration tool for my website. I would like to allow Facebook users to login seamlessly to my website, but also non-Facebook users to creat

Answer 1

Just guessing here - because I had a similar but non-identical problem:

If you use the Facebook XFBML code on http://developers.facebook.com/docs/plugins/registration/ and replace the word {YOUR_APP_ID} by {1234123434534} (or whatever), it fails because it isn't expecting the curly brackets. (Different from various other areas that use JSON and are expecting them).

I don't know if this is what you've done wrong, but it's an easy mistake to make, as I just discovered.
