🔧 Koch Analytics Quick Fix

Issue Identified: The Koch trainer fails to save session results with a 500 error because of a database column mismatch.

📋 The Problem

Your Koch analytics API is trying to insert data into a char_symbol column, but the database table likely has a character column instead (or the tables don't exist at all).

🛠️ Quick Fix Options

Option 1: Run the Diagnostic (Recommended)

🔍 Run Diagnostic Tool

This will show you exactly what's wrong with the database tables.

Option 2: Run the Complete Fix

🔧 Run Complete Fix

This will automatically fix all column name issues and create missing tables.

Option 3: Quick Table Creation (If tables don't exist)

⚡ Create Tables

Use this if the diagnostic shows that tables don't exist at all.

🧪 Test After Fix

Run one of the fix options above
Go to your Koch CW Trainer
Complete a short training session
Check if the session saves successfully (no 500 errors in console)

📊 Expected Result

After the fix:

✅ Koch training sessions will save analytics data
✅ No more 500 Internal Server Error
✅ Analytics will be available at Koch Analytics Dashboard
✅ Console will show: "✅ Advanced analytics saved successfully"

💡 Technical Details: The issue is that the koch-analytics.php API expects a char_symbol column in the koch_character_analytics table, but the table may have been created with a character column name. The fix scripts will rename the column or create the correct table structure.

🔄 If You Still Have Issues

If the fix doesn't work, check:

Database connection in your .env file
User permissions to create/alter tables
Browser console for any remaining errors
