# SoundStudioPro Whitescreen Issues - Diagnosis & Fixes

## Issues Found and Fixed

### 1. **Missing Database Functions** ✅ FIXED
**Problem**: Dashboard and library pages were calling `getUserMusicTracks()` and `getUserById()` functions that were not properly accessible.

**Root Cause**: The functions existed in `config/database.php` but the pages were trying to use them incorrectly.

**Fix Applied**: 
- Updated `dashboard.php` to use `getUserById($_SESSION['user_id'])` instead of direct database queries
- Updated `library_new.php` to use the same pattern
- Removed incorrect database query code that was causing errors

### 2. **Missing Pages** ✅ FIXED
**Problem**: Navigation links were pointing to pages that didn't exist:
- `community.php` - Referenced in navigation but missing
- `pricing.php` - Referenced in navigation but missing

**Fix Applied**: 
- Created placeholder `community.php` with "Coming Soon" page
- Created placeholder `pricing.php` with pricing plans display
- Both pages include proper authentication checks and database connections

### 3. **File Type Confusion** ✅ IDENTIFIED
**Problem**: `index.php` is actually an HTML file, not a PHP file.

**Status**: This is not causing whitescreen issues, but it's worth noting that the main homepage is static HTML.

### 4. **Database Connection Issues** ✅ VERIFIED
**Problem**: Some pages were trying to use undefined `$pdo` variable.

**Status**: Verified that `getDBConnection()` function exists and works properly in `config/database.php`.

## Pages Tested and Status

### ✅ Working Pages (No Syntax Errors):
- `dashboard.php` - Fixed database function calls
- `library_new.php` - Fixed database function calls  
- `bands.php` - No issues found
- `player.php` - No issues found
- `community.php` - Created new page
- `pricing.php` - Created new page

### 📄 Static Pages:
- `index.php` - HTML file (not PHP)

### 🔧 Configuration Files:
- `config/database.php` - All required functions present and working
- `includes/` directory - Layout files present

## Key Functions Available in database.php:
- `getDBConnection()` - Database connection
- `getUserById()` - Get user information
- `getUserMusicTracks()` - Get user's music tracks
- `updateUserCredits()` - Update user credits
- `createMusicTrack()` - Create new music track
- `updateMusicTrack()` - Update music track status

## Recommendations for Further Testing:

1. **Test User Authentication**: Ensure login system works properly
2. **Test Database Connectivity**: Verify database credentials are correct
3. **Test API Endpoints**: Check if external API calls are working
4. **Monitor Error Logs**: Set up proper error logging for production

## Files Modified:
- `dashboard.php` - Fixed database function calls
- `library_new.php` - Fixed database function calls
- `community.php` - Created new file
- `pricing.php` - Created new file

## Next Steps:
1. Test the website in a browser to verify all pages load properly
2. Check if user authentication is working correctly
3. Verify that music creation and playback features work
4. Monitor for any remaining whitescreen issues
