Hi! I lost my previous account, and I try to run your suggested command under my terminal. I got the following exception prompt.

php bin/magento setup:upgrade
                                                                                                      
  [Exception]

Hi

check the permission of the directories it should be writable..

You need to run below commands in sequence manner.

rm -rf generated
rm -rf var/cache
php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento setup:static-content:deploy -f
php bin/magento cache:clean
php bin/magento cache:flush

Hope it helps !

Thanks for all your support here!

Actually I did run the di:compile command then read through the error log from apache.

I found that the permission of config.php wasn’t right so I did a 777 chmop for Magento/*.*

Then everything back to normal now.

Thanks! Again my problem is solved!
