1. Wrong PHP version
Laravel 12 needs PHP 8.2+. Change it in cPanel › Select PHP Version.
2. Folder permissions
Set storage and bootstrap/cache to 775 (folders) so the web server can write logs and cache.
3. Missing PHP extensions
Enable fileinfo, gd, zip and pdo_mysql.
4. Corrupted .env
Open .env in File Manager and make sure values with spaces are wrapped in double quotes.
5. Check the log
The exact error is written to storage/logs/laravel-YYYY-MM-DD.log. Send the last lines to support if you need help.
