Facebook API ID?

Hi I would like my Facebook buttons to work.

Do I need to use my Facebook API ID to get "show send buttons in the articles" to work? and if it is so, where do I find my Facebook API ID?

When I try to use the send button now it says: The page http://www.malenewittenielsen.dk/ could not be downloaded, because the server returned status code 503
and I don't now what this means and can do about it?



Siden http://www.malenewittenielsen.dk/om kunne ikke hentes, fordi serveren returnerede statuskode 503.

No, the APP ID is not necessary to 'Send' button. Looks like script is running properly but problem is in facebook side because 'like' button is working properly.
