Answer 1

I solved it changing user and group of folder var/cache and var/logs, then I cleaned cache:

sudo chown -R www-data:www-data var/logs
sudo chown -R www-data:www-data var/cache

sudo rm -rf var/logs/* var/cache/*

Answer 2

Also check the path. In my case, I had

return dirname(__DIR__) . '../../../../var/cache/

instead of

return dirname(__DIR__) . '/../../../../var/cache/ (missing /)

Answer 3

It is mostly the permission issue.

I have got resolved it on MAC using command: $ sudo chmod -R 777 <path/to/cache/directory>

You might try: $ sudo chmod -R 777 /var/www/sonata/app/cache

I found a similar problem when I was using the PHP symfony as the error picture. I found it after running command

php bin/console cache:clear

I solved it by removed everything inside the folder /app/var/cache
