I have the Facebook Like Button plugin installed on my blog, and up until now, the Send button was showing up, but it just randomly disappeared (I just noticed this).
I figured it was a problem with the plugin perhaps, but I tried manually adding the Facebook Like Button code from their developer website, but it STILL wouldn't show the send button.
You can check it out on there, anyone know what could be wrong -- perhaps something is blocking it :S? Problem with Facebook? Any advice is appreciated as I haven't made any changes to any files recently that could have caused this error.
