the following problem, a script works flawlessly without safe mode, but when safe mode enabled, the row

header("WWW-Authenticate: Basic realm=\"anything\"");

causes very strange error: apache doesn't return anything (no headers, no content) - size 0 (i checked it even through telnet).

when i comment this line, just the HTML message for the incorrect user or password is displayed (which should be displayed when cancel is hit by the user)

the code below is

header("HTTP/1.0 401 Unauthorized");
echo 'incorrect user or password';
die();

I'm not 100% percent sure, but I think it is not error of configuring php

We're having exactly the same problem.  PHP 4.1.1, apache 1.3.22 on Linux (kernel 2.4.14)

I don't want to revert to 4.0.6, so I put a big #if 0 around the code in sapi_add_header_ex() in SAPI.c, in the "WWW-Authenticate" case, where it does special stuff if safe mode is on.  It's a band-aid, but it works (for now)

This bug was fixed a few days ago in CVS
