We logged into your backend of the test site you sent and did the following:
1. Cleared the cache, since JCH Optimizer was still showing up in the page source (as Alex mentioned above)
2. In your site template (shaper_newsplus) under the Advanced section, the 'Javascript Compression' option was still enabled. We disabled it and this cleared up the error that our jfbconnect javascript was not defined.
If you look at
test.setupmyhotel.com/forum/register.html you can see that clicking on the social network buttons like Facebook now work.
Please update your template setting for Javascript Compression and disable JCH Optimize for JS compression on the live site and I think this should fix your issue.
