Mahara: Site unavailable
Your defined data root directory, /var/www/upload/, is not writable. This means that neither session data, user files nor anything else that needs to be uploaded can be saved on your server. Please make the directory if it does not exist or give ownership of the directory to the web server user if it does.
(Your server has the php open_basedir restriction enabled. Mahara can only open files within the following path(s): /var/www/clients/client3/web3/web:/var/www/clients/client3/web3/private:/var/www/clients/client3/web3/tmp:/var/www/ultramarin-group.ru/web:/srv/www/ultramarin-group.ru/web:/usr/share/php5:/usr/share/php:/tmp:/usr/share/phpmyadmin:/etc/phpmyadmin:/var/lib/phpmyadmin:/dev/random:/dev/urandom.)
