My trackback links quit working

This is the link structure of my trackbacks as they show up in my pages. http://www.frankrobinson.com/wp-trackback.php?p=52

When you click the link, you go to this page…..
http://www.frankrobinson.com/wp-trackback.php?p=52
that has this text:
OK
The document has moved here.
Apache/1.3.29 Server at http://www.frankrobinson.com Port 80

If you click the “here”, which is a link, it takes you to:
http://www.frankrobinson.com/?p=52

which is the correct page.

It was working fine (It was going directly to the correct page) then it stopped. Anybody got any ideas????
