Hi @kai_dh 

There might be some permission issue.
https://devdocs.magento.com/guides/v2.3/config-guide/prod/prod_file-sys-perms.html

Try the following command once:

find . -type d -exec chmod 755 {} \; && find . -type f -exec chmod 644 {} \; && chmod u+x bin/magento

You can use sudo as well.

If still face issue, then try following command s once to re generations.

composer update

chmod -R 0777 var/ pub/ generated/
rm -rf var/cache/* var/view_preprocessed/* generated/* pub/static/*
php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento setup:static-content:deploy -f
php bin/magento cache:flush

I hope it will help you!

Hi, thanks for you reply.

It's installed on a webhosting. Any other way to fix this?

Hi @kai_dh 

It is required to run the commands for magento setup.

@kai_dh 

Clear all directories and files under Magento's var subdirectory and install the Magento software again.

As the Magento file system owner or as a user with root privileges, enter the following commands:

$ cd <your Magento install directory>/var

$ rm -rf var/cache/* di/* generation/* page_cache/*

Redis

If you use Redis and still get an error, clear the Redis cache as follows:

$ redis-cli FLUSHALL 

[kai_dh]

Alright, what is the recommended operation system?

e.g. CentOS
