The script whose uid is 33 is not allowed to access /tmp owned by uid 0

If SAFE MODE is on in PHP, the owner ID of the PHP file needs to be same to any folder or file it tries to access. So if you try to use sessions and if your PHP is configured to use /tmp folder for saving session data it can cause error shown in title of this blog post.

To fix it check following directive is set as follows

session.save_path = /tmp

If yes create folder


change owner of the above folder to same as that of the web server, so for e.g. you would say

chown www-data:www-data /var/lib/php5/session

now change /etc/php.ini  or /etc/php5/apache2/php.ini

to use following setting

session.save_path = /var/lib/php5/session

now reload web server e.g.

service apache2 reload


/etc/init.d/apache reload

This should fix the problem
