And after the execution of this command My site returning HTTP ERROR 500.

Any Idea how to solve this ??

Answer 1

Enable the developer mode. By running the below commend.

php bin/magento deploy:mode:set developer

after that you can see the errors trace in frontend.

Answer 2

For the unexpected 500 error, we should enable error reporting on the bootstrap. Should enable error reporting with -1 value. That will report all PHP errors.

app/bootstrap.php

ini_set('display_errors', -1) // Should enable error reporting with -1 value.
