Answer 1

This solution is correct for me: https://stackoverflow.com/a/39782535/2400373

But If you do not have access to the terminal, you can enter the server and delete the folders that are inside var/cache.

Another solution if you have access to the console is to type

#rm -rf var/cache/*

or

$sudo rm -rf var/cache/*

this solution works on symfony 3
