  • Go to your var/ directory and set permission specially for page_cache directory to 777. Sep 6, 2018 at 11:12

I have faced same type of error few days ago.

You can fix it by following ways..

chmod 777 -R var/ generated/(root access if don't have root access try with sudo)

NP: *****you need to give permission every time when you use below cmd.*****

php bin/magento cache:flush

So, you need to give proper permission of your application . you can follow below links.
