Disqus block not rendering

Hello, I have installed the modual 'Disqus' for commenting. I have assigned a block, and selected the correct node types for this to display. I have checked user permissions to allow display of Disqus comments. I have then flushed all Cache's. When the page loads, the block does load but nothing visible. I have checked with firebug and this is the code that comes up. <p><a href="http://http://sunseavip.disqus.com.disqus.com/?url=http%3A%2F%2Fwww.sun…">View the discussion thread.</a></p> Why is there a tag? Please advise. Thanks
