Error 500 while setting website,store

Hi lakvenkat,
That is a strange issue. Let’s provide me the admin credentials, ssh credentials and web root folder path of your Magento2.
I will check further and help you out.

Hi lakvenkat,
I have detected your working and i see you have some wrong setting with folders/files permission.
The ssh credentials you have provided has not permission to re-chmod for that.
Let’s re-chmod & change the owner of folders/files in the folder at: /var/www/html/usmig
You should change to owner www-data  by command:
chown -R www-data:www-data /var/www/html/usmig
And then, re-chmod for that by commands:
find /var/www/html/usmig -type d -exec chmod 755 {} +;
find /var/www/html/usmig -type f -exec chmod 644 {} +;
And tell me know how it goes.
Regards,
Mall.
