Your cache folder seems to be not writable by Apache webserver (as it should). Make sure you’ve run these commands from the your hoster’s command line (ssh):
sudo chown -R www-data:www-data . #the user name your webserver uses.
sudo chmod -R 755 .
sudo chmod -R 775 cache custom modules themes data upload
sudo chmod 775 config_override.php 2>/dev/null
