Summary + +## Problem Addressed + +Users were experiencing intermittent errors when clicking "Pay from PayPal" button: +- **JSON parsing errors** +- **HTTP ERROR 500** +- **"Currently unable to handle this request"** errors + +These errors would "flip-flop" between different types, making diagnosis difficult without proper logging. + +## Solution Implemented + +Added comprehensive logging throughout the entire PayPal payment flow to capture: +- All request/response data +- Error details with full context +- Unique request IDs for tracking +- Database operations and results +- Client-side JavaScript errors + +## What Changed + +### Modified Files + +1. **`api/create_order.php`** - Enhanced with comprehensive logging + - Logs every step of order creation + - Captures request data, OAuth process, PayPal API calls + - Returns request IDs in error messages for tracking + - Logs to: `logs/paypal_create_order.log` + +2. **`api/capture_order.php`** - Enhanced existing logging + - Logs payment capture process + - Tracks database operations (invoice updates, order creation) + - Captures all error conditions + - Logs to: `logs/paypal_capture.log` + +3. **`cart.php`** - Improved client-side error handling + - Better error messages with reference IDs + - Enhanced console logging for debugging + - Sends errors to server for centralized logging + - Better user feedback during payment process + +4. **`api/log_error.php`** - NEW: Client error logging endpoint + - Captures JavaScript errors from browser + - Logs to: `logs/client_errors.log` + +### New Files + +1. **`PAYPAL_DEBUGGING_GUIDE.md`** - Comprehensive debugging guide + -

Check `PAYPAL_DEBUGGING_GUIDE.md` for common issues +2. Review `QUICK_DEBUG_REFERENCE.md` for quick fixes +3.
