I have been having the same problem. I don't know how kosher this is, but I made mine work:
Find your FaceBook 'Like' block in code view:
<div class="wasocial_facebook_like">
<script src="http://connect.facebook.net/en_US/all.js#xfbml=1"></script>
<fb:like href="http://www.yeractual.com/like.php" layout="standard" show_faces="false" width="450" action="like" font="arial" colorscheme="light"></fb:like>
Cut and paste the second line ( <script src="http://connect.facebook.net/en_US/all.js#xfbml=1"></script> ) in to the head area of your page. For good measure (but not entirely necessary, I have found) add type="text/javascript" to the javascript line, i.e:
<script type="text/javascript" src="http://connect.facebook.net/en_US/all.js#xfbml=1"></script>
</head>
You would of course paste your own line.
That should make both appear on your page.
