We are a site located in Belgium. We added the 'locale=nl_BE' parameter to our iframe like button so it says like but in the Dutch language (= "vind ik leuk").
This no longer works. When we change the locale to nl_NL (also Dutch language) the like button works again.
When I check the Facebook Internationalization documentation I can't seem to find Belgium or nl_BE, strange right? This worked for months until yeaserday. http://www.facebook.com/translations/FacebookLocales.xml

Facebook just closed the bug report I had posted about the nl_BE issue.
"This locale is not currently supported. But you should be able to load the plugin even if a locale is not supported, it will fallback to en_US locale."

That's just plain silly. The change I see compared to a few months ago is that (as is mentioned in the comment on the bug) share buttons no longer break when you pass an unsupported locale but fallback to en_US.
They should get their language/locale act together.
