Thank you, Daniel. Inserting a call to debug_print_traceback() (with a terminating semi-colon) at the top of the ErrorHandler404() function produces no visible output (and nothing in the application directory or in ~/). Will someone suggest either how I properly use debug_print_traceback() or otherwise learn what's failing as I try to invoke the application and transferring control to the error handler? There has to be something either in the index.php, or a function it's calling, that cannot find the opening display. I need to learn what's happening so I can get this application running here.

[PHP] Debugging Help Needed
I'm not a PHP coder, but I have an application written in PHP (CMS Made
Simple) that stopped working when I upgraded postgres to 9.x. I seem to have
most of the problems fixed (those with adodb_lite) but now need to track
down why I get a 404 Page Not Found error when I try to invoke the local
application. BTW, I'm running php-5.2.17 on Slackware-13.1.
Running 'php index.php' from the application subdirectory to the document
root directory, I learn the code to search in the directory structure. It
turns out to be misc.functions.php, and the specific function in that file
is ErrorHandler404(). However, I have not been able to trace execution to
learn just where this function is being called.
Looking at the PHP manual I see there's a function called
debug_print_backtrace(), but I have not found how to properly use it. When I
insert it at the top of ErrorHandler404(), php throws an error when I try to
run index.php:
function ErrorHandler404()
{
debug_print_backtrace()
#if ($errno == E_USER_WARNING) {
@ob_end_clean();
header(HTTP/1.0 404 Not Found);
header(Status: 404 Not Found);
echo '!DOCTYPE HTML PUBLIC -//IETF//DTD HTML 2.0//EN
htmlhead
title404 Not Found/title
/headbody
produces:
PHP Parse error: syntax error, unexpected '@' in
/var/www/htdocs/cmsms/lib/misc.functions.php on line 223
How can I determine where ErrorHandler404() is being called so I can fix
the problem and get the application running again?

You missed the ending semicolon, that's all. So when this line comes up:
@ob_end_clean();
PHP completely flips its lid and starts making threats against your life.

Adding that, I remove the error but do not see the printed backtrace. Please suggest how I can determine the source of the page not found error, or how to capture output from debug_print_backtrace.
