I was using Apache 2.0.39 with php 4.2.2 and everything was going fine. When i change to Apache 2.0.40 with 4.2.3 with the same configurantion, the function file_exists do not work anymore.

This is the part of the script:

if (!file_exists("subs/$sub.htm")) {
   $op = fopen("/home/httpd/sistema/logerror.txt", "a");
      $ins = fputs($op, "Try accessing $sub.htm\n");
   $close = fclose($op);
   Header("Location: portal.php?sub=error");
   exit;
}
