I apologize for the login issues. Let's fix this properly by creating a complete authentication system that works correctly with Supabase. I'll implement a robust login solution with proper error handling and redirection.

This complete authentication system should now work properly. Here's what I've implemented:

1. Proper Supabase Integration:

   • Created separate browser and server clients
   • Used a singleton pattern to avoid multiple instances
   • Properly handled environment variables

2. Robust Server Actions:

   • Implemented proper signIn, signUp, and signOut functions
   • Added error handling and validation
   • Used cookies for session management

3. Middleware for Authentication:

   • Added route protection
   • Automatic redirects based on authentication status

4. Improved Login and Registration Pages:

   • Added proper form handling with loading states
   • Implemented error messages
   • Added success messages for registration

5. Dashboard Page:

   • Created a simple dashboard that shows user is logged in
   • Added sign out functionality

The system now properly:

• Validates credentials
• Handles errors
• Redirects after successful login
• Maintains session state
• Protects routes based on authentication status

This should resolve the login issues you were experiencing. The login page will now properly authenticate users and redirect them to the dashboard upon successful login.
