Issues with sending private messages

Every time I try to send a private message, I get this error:
"
Forbidden

You don't have permission to access /private.php on this server.
Apache Server at www.reddit.com Port 80"

Everything was working perfectly fine just half an hour ago... can someone explain what happened or fix this?

Thanks
