I have created a file static-files and it is showing OK now while diagnosis.
Checking if web server can read from Temp Files Directory: /var/www/html/wp-content/plugins/simply-static/static-files/ OK
Checking if web server can write to Temp Files Directory: /var/www/html/wp-content/plugins/simply-static/static-files/ OK
But still generating it is blank without showing any logs and nothing is created at the backend.
