weird require() problem

Hi, My script will not require a certain file. It has the same permissions as every other file in the same directory, and they are all require()ed fine. Here's the directory listing: -rw-r--r-- 1 nobody nobody 8937 Jul 7 12:57 gazz_signup.html -rw-r--r-- 1 nobody nobody 6716 Jun 3 10:10 help.html -rw-r--r-- 1 nobody nobody 507 Jun 3 10:10 moore.html The file I want to require is gazz_signup.html, but I get this error in the source and the page stops loading: Failed opening required '/usr/local/apache/htdocs/megsoc2/gen/gazz_signup.html' (include_path='/apache/inc') in.... help.html gets require()ed fine, even if I change it's name to gazz_signup.html. If I change gazz_signup's name to help.html, it fails with the above error. I am completely flummoxed by this, this is bizarre. Any ideas? - Kev
