Strange "Red X" problem.

[TripMaster]

We have both RPP and PPP and RPP is working fine.

If you go to this page here, which I guess I'll call "home", everything looks fine:
http://www.mousetrip.net/pp/index.php

(make sure the skin selector is set to "mousetrip.net 9")

If you go to this page here, which I'll call "TopCat1", I get a "Red X" next to where it says "MouseTrip.net" among other things:
http://www.mousetrip.net/pp/index.php/cat/536

It's pointing to here:

If you go down one more level, I'll call it "TopCat1-SubCat1" I get another "Red X" next to where it says "MouseTrip.net" among other things:
http://www.mousetrip.net/pp/showgallery.php/cat/2

It's pointing to here:

Why is it doing that and how do I fix it?
Thanks.

Disregard, turned off Spider friendly URLs and it fixed it.
Thanks Chuck!
