Did you try typing http://www.talkmorgan.com in the address bar?
I found that worked on my wife's Mac. I have half an idea that the problem is occurring when the browser is incorrectly trying to directly link to a file which is in a sub-folder. Note the original link which was given in my first error message: "You don't have permission to access /ubbthreads.php/forum_summary on this server." It could also be a problem relating to how php is trying to interpret the parameter "forum_summary" as set out in the forum script.

There are others who are more up to date than me on this and may be able to suggest the probable cause.
