LinkedIn is actually much more picky about the www vs non-www stuff. Some of their widgets (member profile, company insider, etc) will -only- work on what you've set as your Javascript URL in the application configuration. The login functionality will work for either though.

To fix, we'd highly recommend setting up a redirect from the www to non-www (or the other way, whatever you prefer). If you're using the .htaccess file, this can be done by adding the following lines toward the top (this is ours which forces www):There are also addons for Joomla which can do the same thing.

With that said, to fix just within Facebook, you should be able to do that by making sure your "Domain URL" in your Facebook Application is set to: linksknowledge.com

That will allow the Facebook buttons to work on your main domain and any subdomains (www is considered a sub-domain).

Hope that all helps, and isn't too complex. It can get tricky, so if you have any questions, just let us know!

Thanks,
