Laravel Cache Not Working? Fix Common Issues Step-by-Step (Complete Guide)

What Is Cache in Laravel?

Cache stores frequently used data temporarily so Laravel doesn't need to query the database repeatedly.

Laravel supports multiple cache drivers:

• file
• database
• redis
• memcached

Why Laravel Cache Is Not Working

• ❌ Cache not cleared after updates
• ❌ Incorrect cache driver
• ❌ .env changes not applied
• ❌ File permission issues
• ❌ Config caching conflicts
• ❌ Deployment mistakes

Fix #1 – Clear Application Cache

php artisan cache:clear
php artisan config:clear
php artisan route:clear
php artisan view:clear

✅ This solves most issues instantly.

Fix #2 – Config Cache Issues

If config is cached, Laravel ignores .env changes.

php artisan config:clear
php artisan config:cache

Fix #3 – .env Not Updating

php artisan config:clear

❗ Never use env() directly outside config files in production.

Fix #4 – Wrong Cache Driver

CACHE_DRIVER=file

• Redis not installed but used
• Database cache table missing

php artisan cache:table
php artisan migrate

Fix #5 – File Permission Issues

chmod -R 775 storage
chmod -R 775 bootstrap/cache

💡 Very common production issue.

Fix #6 – Cache Problems After Deployment

php artisan optimize:clear
php artisan config:cache
php artisan route:cache

If using queues:

php artisan queue:work

Debugging Checklist

Best Practices

• Always clear cache after deployment
• Use Redis in production
• Avoid using env() in application code
• Automate cache clearing in CI/CD
• Monitor cache performance
