Solution 1

usually it means you have a wrong path in session.save_path parameter in Apache config or php.ini

try to set

ini_set("session.save_path", "/path/to/tmp");

in the beginning of your file. If it helps, edit your php.ini file, otherwise try to find it somewhere, maybe in VirtualHost section

Solution 2

You just need to give permission to access this directory.

On Windows, just open the directory and the system will ask you to change permission to it.

Seems like everyone involved on this question missed the fact that PHP was configured to use memcache as the session handler. File paths aren't relevant to using memcached for session storage. The session.save_path is supposed to be a comma-separated list of hosts and ports.

ok i have found the solution libraries/session.inc.php at line 79 // session.save_handler ini_set('session.save_handler', 'files'); Commenting out this line, everything works fine.
