Error Messages Again?

[Defrost]

I know this has happened in the past, but I just wanted to post and say it's happening again, just to let you know. :) Whenever I click on a link to open a thread, I get an error message. When I re-fresh to open it again, it works fine the second time.

This is the message I get:

Safari can’t open the page “http://www.car-seat.org/showthread.php?p=592900#post592900”. The error was: “bad server response” (NSURLErrorDomain:-1011)

I'm on a Mac.
