The framework works well here with correct setup.
THE DOCUMENT ROOT
Point the domain's document root at the application's public directory, not the project root.
cPanel > Domains > Manage > Document Root.
If the project root is served, your .env file, source code, vendor directory and storage are all publicly reachable. This is the single most serious Laravel deployment mistake.
VERIFYING
Visit yourdomain.com/.env in a browser. You must get Forbidden or Not Found, never content.
CONFIGURATION
APP_ENV set to production APP_DEBUG set to false, always, on a live site APP_KEY set and unique APP_URL set to the https URL
Debug mode on production exposes environment variables and stack traces to anyone who triggers an error.
PERMISSIONS
storage and bootstrap/cache must be writable: 755 with correct ownership, never 777.
DEPENDENCIES
Install with Composer using the no-development flag on production.
SCHEDULED TASKS
One cron entry running the scheduler, which dispatches your defined tasks.
