Magento has a Blank page after installing sampledata:deploy & upgrade

I tried increasing and change php memory_limit and cleared cache and session

This is the error from magento root index.php

Fatal error: Uncaught RuntimeException: Can’t create directory /var/www/html/generated/code/Magento/Framework/App/ResourceConnection/. Class MagentoFrameworkAppResourceConnectionProxy generation error: The requested class did not generate properly, because the ‘generated’ directory permission is read-only. If — after running the ‘bin/magento setup:di:compile’ CLI command when the ‘generated’ directory permission is set to write — the requested class did not generate properly, then you must add the generated class object to the signature of the related construct method, only. in /var/www/html/vendor/magento/framework/Code/Generator.php:135 Stack trace: #0 /var/www/html/vendor/magento/framework/Code/Generator/Autoloader.php(35): MagentoFrameworkCodeGenerator->generateClass(‘MagentoFramewo…’) #1 [internal function]: MagentoFrameworkCodeGeneratorAutoloader->load(‘MagentoFramewo…’) #2 [internal function]: spl_autoload_call(‘MagentoFramewo…’) #3 /var/www/html/vendor/magento/framework/Code/Reader/Class in /var/www/html/vendor/magento/framework/Code/Generator.php on line 135

I was looking on xml and core file, would it be the layout issue? I would like that to be showing dummy sample product, but I’m ending up with a blank page.

  1. Go to your root directory and fire below command.
    There is just issue with folder permission.

    sudo chmod -R 777 generated/*

  2. Permissions on the folders, and depending on magento version and your storeview (default country/language) use the -f (force) function and use the country code specified in the delpoy comment.

    I have three storeviews so I use the command:
    php bin/magento setup:static-content:deploy -f nl_NL de_DE en_US

  3. it should be:

    sudo chmod -R 777 *
    

    in the htdocs/your-magento-folder
