The Facebook Connect cross-domain receiver URL (<!-- m --><a class="postlink" href="http://clockworkgreen.com/index.php?option=com_jfbconnect&view=xdreceiver&format=raw#fname=_opener&%7B%22t%22%3A3%2C%22h%22%3A%22fbCancelLogin%22%2C%22sid%22%3A%220.535%22%7D">http://clockworkgreen.com/index.php?opt ... .535%22%7D</a><!-- m -->) must have the application's Connect URL (<!-- m --><a class="postlink" href="http://www.clockworkgreen.com/">http://www.clockworkgreen.com/</a><!-- m -->) as a prefix. You can configure the Connect URL in the Application Settings Editor.
That's the error I get when trying to use Facebook Connect on your site.
My site has the redirect loop error. Before that I had the avatar error.... hoping this will be fixed quickly as it is a totally cool plugin for jomsocial.
