Introduction

As a web development agency, we’ve seen it all — websites crashing just before launch, buttons not working after an update, or users suddenly being locked out. Most of these issues come down to a handful of common bugs that can be fixed quickly — if you know where to look.

In this article, we’ll break down the top 5 bugs that break websites, how to identify them, and how to fix them fast — saving you time, money, and stress.

1. JavaScript Conflicts

Symptoms: Buttons not working, dropdowns fail, console errors.

Cause: Multiple versions of jQuery or script load order issues.

Fix: Check the browser console (F12 > Console), remove duplicate scripts, ensure proper load order using defer or $(document).ready().

2. CSS Broken Layouts

Symptoms: Layout looks broken on mobile/desktop, elements overlap.

Cause: Conflicting or missing classes, broken responsive code.

Fix: Inspect using browser dev tools, verify HTML structure, and fix unclosed tags. Use responsive design tools for cross-device checking.

3. Database Connection Errors

Symptoms: SQLSTATE errors, blank pages, missing data.

Cause: Wrong DB credentials or misconfigured Laravel cache.

Fix:

                            
                            DB_HOST=127.0.0.1
                            DB_PORT=3306
                            DB_DATABASE=your_db
                            DB_USERNAME=root
                            DB_PASSWORD=secret
                            php artisan config:clear
                            php artisan config:cache
                            
                        

4. Permission or Auth Errors

Symptoms: 403/401 errors, login not working, file upload issues.

Fix: Check route middleware, fix Linux file permissions:

chmod -R 755 storage/
                            chmod -R 755 bootstrap/cache/

Also ensure SESSION_DRIVER=file is set in your `.env` during development.

5. 404 Pages or Routing Errors

Symptoms: Route works locally, not on server; page not found.

Fix:

php artisan route:clear
                            php artisan route:cache
                            php artisan route:list

Ensure your route names match your blade files and frontend URLs.
