My PHP version is 4.3.2.
Any help PLEASE???
Are you using PHP 4.3.2 or 4.4.2 (which is the latest 4.x version)?
From the PHP manual (http://www.php.net/ref.session#ini.session.save-path):
LainaaNote: Prior to PHP 4.3.6, Windows users had to change this variable in order to use PHP's session functions. A valid path must be specified, e.g.: c:/temp.
If you are using 4.3.2, I recommend upgrading to 4.4.2 ASAP as 4.3.2 is really old. If you are using 4.4.2, then make sure the session.save_path is valid and that this directory is writable (the "IUSR_{machinename}" user needs to have Read, Write and Modify access on that directory - {machinename} = the name of your computer).
