Why am I getting a 404 error on all routes except the homepage?

Answer: Your .htaccess or Nginx config may be incorrect. Laravel needs URL rewriting to route requests to index.php.

Apache (.htaccess) Solution:

Ensure your .htaccess file in the public directory contains:

    RewriteEngine On
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^ index.php [L]

Nginx Configuration:

location / {
    try_files $uri $uri/ /index.php?$query_string;
}

Check mod_rewrite:

For Apache, ensure mod_rewrite is enabled:

sudo a2enmod rewrite
sudo systemctl restart apache2

Laravel Route Cache:

Clear route cache if you're using route caching:

php artisan route:clear
php artisan config:clear
