This is permission issue. Just set below permission to folders

find . -type f -exec chmod 644 {} \; // 644 permission for files

find . -type d -exec chmod 755 {} \; // 755 permission for directory

find ./var -type d -exec chmod 777 {} \; // 777 permission for var folder

find ./pub/media -type d -exec chmod 777 {} \;

find ./pub/static -type d -exec chmod 777 {} \;

chmod 777 ./app/etc

chmod 644 ./app/etc/*.xml


Run this command below

php bin/magento cache:flush

php bin/magento cache:clean

chmod -R 777 var/ pub/


If it is Magento 2.2 please run this command below

php bin/magento cache:clean
php bin/magento cache:flush
sudo chmod -R 777 var/ pub/ generated/
