there has been a change in my server apache/php 4.4.9/mysql effected
by my web hosting company that i can't figure out.
there first symptom is that the authentication form for users to log
in doesn't work at all (it worked a few days ago, and it has been
working for more than a year now).
the second weird behaviour is that when i placed this:
print_r ($_POST);
on the page where the login information is going to it retuned an
empty array.
what can it be that they have changed that causes this problem?
thank you in advance for your help,

What does phpinfo() output? Anyway, it sounds like your host has set
up phpsuexec or suPHP o rsomething similar where PHP runs in the CGI
API, rather than the Apache (or web server) API, since Basic auth in
scripts
doesn't work the same way, by default in the CGI API. That's just a
guess and this doesn't mean a bad thing, other than some changes might
be needed in your script(s). The other sounds like they have disabled
register_globals, which is also a good thing, but might require some
changes.
They might have also upgraded to PHP5, which has some of these
settings by default (again, a good thing, provided you use decent
scripts, but
otherwise could demand a few changes). Check with them, that's your
best bet and as your web host, they should be the best people to help
you, and the most willing. Did they fail to provide a notice of these
impending changes? Are they not communicating the changes they've
made?
Hi Tim,
thanks for your prompt response.
i checked a different script that uses $_POST and it works. which
prompted me to check if the problem was with $_SESSION and it seems
that's where the problem is.
when i tried to start the session, immediatelly after the <?php not to
output any characters before the session starts i got this error
message:
Warning: session_start() [function.session-start]:
open(/tmp/sess_da16eee0d2368adc760940fb27db29af, O_RDWR) failed:

i checked phpinfo() and the php version is 4.4.9 (i believe they used
to run 4.4.6, but i'm not sure). register_globals is off,
register_argc_argv is on. i don't remember if this has changed, but
i'm quite sure that my log in doesn't rely on register_globals being
on.
this is the output for session in phpinfo()

it's hard for me to knwo whether this has changed or not...
also in enviroment they show:
SERVER_SOFTWARE Apache
thank you again for your help,
NN
The environment might have changed, or the /tmp partition is full (or
the partition /tmp is on), or any number of things. You'd need to
contact your host, as we could only guess from here.
