What's the difference between a 500 Internal Server Error and other display errors in Laravel, and how do I troubleshoot each?

A 500 Internal Server Error indicates a general server-side error. Troubleshoot it by checking the Laravel logs (`storage/logs/laravel.log`) and server error logs. Other display errors might be related to specific code issues, route problems, or environment configuration. Check the logs, environment settings, and Artisan commands for cache clearing and configuration optimization to resolve these problems.
