FAQ link problem: CSS and shortcodes

I’ve been trying to find out what shortcodes are available and how to use them, and CSS recommendations, but there seems to be a problem with the FAQ links.
http://businessdirectoryplugin.com/support-forum/faq/how-to-use-custom-styles-with-bd-2-1/
http://businessdirectoryplugin.com/support-forum/faq/valid-bd-shortcodes-2-1/

I get this message:
The page isn’t redirecting properly
Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

Would you please repair them?

Thanks!
