Answer 1

Please check code around:

// optionally set session_save_path
$path = $GLOBALS['PMA_Config']->get('SessionSavePath');
if (!empty($path)) {
    session_save_path($path);
}

You may try commenting it out and test one more time (implementation of session_save_path() is not posted here and I suspect that the issue is there).

Answer 2

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.

Answer 3

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.

Answer 4

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
