[kumarsena]

had a simple skinning script thta was running by choosing css files. my host updated teh php and all of a sudden im getting these warnings...

Warning: session_start(): open(/var/lib/php/session/sess_045fa8dd77d74364c16cb915688a7a8c, O_RDWR) failed: Permission denied (13) in /mnt/home2/k/ku/kumar/public_html/index.php on line 2

Warning: Unknown(): Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/var/lib/php/session) in Unknown on line 0

can anyone tell me what this all means, please....?

my session code on TOP of all pages is like this:

<?php
session_start();

//session code for skins
//header('Cache-control: private'); //IE 6 Fix

if ( isset($_SESSION['skin']) ) {

$skin = $_SESSION['skin'];
}

else {
$skin = "flyaway_yellow3.css";

}

//end session code

thanks

It looks like your host may not have set permissions to the directory /var/lib/php/session/ properly. I have never had this problem myself, but this is the only plausible cause I can think of. You can try:

<?php
echo 'Dear Host,<br />
Some moron on webmasterworld's php forum told me sending this information to you might help out my sessions problem.<br />

Sessions directory is set to: /var/lib/php/session/ <br />

file owner: '.fileowner(/var/lib/php/session).'<br />
file group: '.filegroup(/var/lib/php/session).'<br />
file permissions: '.fileperms(/var/lib/php/session).'<br />
current script user: '.getmyuid().' group: '.getmygid().'<br />'
<br /><br />Cheers!<br />Kumar
?>

These 'permissions' are in numerical format - first a number you can probably ignore, then owner, group, and file permissions numbers - your php scripts will be running under a certain 'user' and 'group', and if neither user nor group has permissions to do something with a file (read it or write it), they won't be allowed to and you get permissions errors. The numbers correspond to:

0 = Nothing
1 = Execute
2 = Write
3 = Execute & Write (2 + 1)
4 = Read
5 = Execute & Read (4 + 1)
6 = Read & Write (4 + 2)
7 = Execute & Read & Write (4 + 2 + 1)

Your host will probably have to re-set the permissions on this directory (or else change the apache user you're running).
