include error with no includes

I've got a few php pages that a while back started giving the following include error: Warning: Failed opening '/home/ccunning/WWW/probability.php3' for inclusion (include_path='.:/web/php/include:/web/php/phplib') in Unknown on line 0 There are no includes in this page, there is no auto-prepend file defined. Why is it trying to include the page from an Unknown file? Why aren't all the pages doing this? I have seen this on two different machines, both Linux, both were running php 4.0.4p1 and updating both to 4.0.6 didn't fix it... -- Chad Cunningham ccunning@math.ohio-state.edu "Well, once again my friend, we find that science is a two-headed beast.
