We're having some trouble getting our like button to work. It seemed to work last week but suddenly it's stopped working.
Basically when clicking "Like", we get an error saying:
You failed to provide a valid list of administators. You need to supply the administors using either a "fb:app_id" meta tag, or using a "fb:admins" meta tag to specify a comma-delimited list of Facebook users.
Our section looks like this:
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:og="http://opengraphprotocol.org/schema/" xmlns:fb="http://www.facebook.com/2008/fbml" xml:lang="en" lang="en">
<head>
<meta property="fb:app_id" content="number"/>
<meta property="fb:admins" content="number"/>
<meta property="og:title" content="title"/>
<meta property="og:type" content="website"/>
<meta property="og:url" content="url with trailing slash"/>
<meta property="og:image" content="url to image"/>
<meta property="og:site_name" content="Site Name"/>
</head>
Help?
