F Connect button frozen

Did you try the troubleshooting section of readme.txt?

You can leave the <fb:like> tag in your block. Just don't put the <script> tag for all.js. modules/fb will initialize the javascript for you.

I don't have a script tag for all.js on a page. But still I am getting "fb_devel.js: Facebook JS SDK initialized witout app id" alert too.

It was working without any problem before, when I was using 6.x-3.0.

Here is my page-source: http://pastebin.com/pZrxhqA0

Sometimes that message pops up because of a race condition, even when there is no problem. I want to fix that, but it should only cause that problem for users with access to devel info. If you're not seeing other problems, you can safely ignore that popup.

I have found the solution for my problem;
I was using custom login buttons:

			<div id="fb-connect-button">
				<a href='#' id='login' class='fbconnect-link' />Login</a>
				<script type='text/javascript'>
				    $('#login').click(function(event) {
				        FB.login(function(response) {
				            if (response.session) {
				            	//user logged in
				            } else {
				                // user cancelled login
				            }
 				       }, {perms: 'email'});
				    });
				</script>
			</div>

But when I compare the working button in the "fb_devel block" and the one in the "fbconnect" block:

FB_DEVEL: <fb:login-button  scope="email"><fb:intl>Connect</fb:intl></fb:login-button>
FBCONNECT: <fb:login-button perms="email" v="2">Connect</fb:login-button></div>

When I replaced "perms" with "scope" in my custom code, connect button started to work.
