I do not get a message about javascript needing enabled… its running for me… but you do have jquery issues…
see: http://codex.simple-press.com/codex/faq/troubleshooting/what-is-this-jquery-conflict/
namely, you have a plugin incorrectly loading jquery…
<script type=’text/javascript’ src=’http://cdn.itler.net/wp-content/plugins/slidedeck2-personal/js/slidedeck.jquery.js?ver=1.4.1′></script>
its loading its own very old/ancient version of jquery… wp comes with v1.8.3 and plugins will be expecting this wp tested and up to date version…
you also appear to be running a minify plugin which is likely screwing up js further… since sp comes with minified js already, these minify plugins tend to screw it up…
so two things to do… tell minify not to minify our scripts… and get the plugin to load the wp version of jquery instead of its out dated version… is that slide deck plugin even doing anything on the forum page??? seems like only on the front page so it shouldnt even be loading its stuff on every page… but if you can find where its loading its own jquery, we can help you fix it…
