# Recent Fixes & Enhancements Summary
**Date:** November 10, 2025

## Critical Fixes Completed ✅

### 1. PayPal Payment Capture Session Issue (FIXED)
**Problem:** Payment capture was failing with `NO_USER_SESSION` error even though user was logged in.

**Root Cause:** The `api/capture_order.php` file was calling `session_start()` without setting the session name first, so it couldn't access the `gameservers_website` session where the user_id is stored.

**Solution:** Added `session_name("gameservers_website")` before `session_start()` in `capture_order.php`.

**File Modified:** `modules/billing/api/capture_order.php` (line ~148)

**Test Steps:**
1. Log into the billing site
2. Add a server to cart
3. Click PayPal checkout button
4. Complete payment in PayPal sandbox
5. Verify payment completes successfully and redirects to success page
6. Check `modules/billing/logs/payment_capture.log` - should no longer show `NO_USER_SESSION` error

### 2. Cart Page Debug Logging Removed (COMPLETED)
**What Was Removed:**
- Shutdown function that logged to `data/debug_cart.log`
- `?debug_cart=1` parameter handling
- Debug error display code

**File Modified:** `modules/billing/cart.php` (lines 1-30)

**Result:** Cart page now runs in production mode without debug overhead.

---

### 3. Cart Page Header/Footer Consistency (FIXED)
**Problem:** Cart page had different fonts and styling than other billing pages; missing footer entirely.

**Solutions Applied:**
1. Added `include(__DIR__ . '/includes/top.php');` before menu
2. Added `include(__DIR__ . '/includes/footer.php');` at page end
3. Removed global `font-family` and `background` override from inline CSS
4. Added favicon links to match other pages

**Files Modified:**
- `modules/billing/cart.php` (head section and body closing)

**Result:** Cart page now has consistent header/menu/footer with rest of billing module.

## Remaining Documentation Work 📋

### Games Needing Full Port/Parameter/Troubleshooting Docs

The following games need their `docs/{game}/index.php` files updated with the Minecraft template pattern:

#### High Priority Games (Popular):
1. **Counter-Strike: Global Offensive** (`csgo/`)
2. **Team Fortress 2** (`tf2/`)
3. **Garry's Mod** (`garrysmod/`)
4. **Rust** (`rust/`)
5. **ARK: Survival Evolved** (`arkse/`)
6. **Terraria** (`terraria/`)
7. **Valheim** (`valheim/`)
8. **7 Days to Die** (`7daystodie/`)
9. **DayZ** (`dayz/`)
10. **Left 4 Dead 2** (`left4dead2/`)

#### Medium Priority:
11. Counter-Strike Source (`css/`)
12. Arma 3 (`arma3/`)
13. Squad (`squad/`)
14. Insurgency Sandstorm (`insurgencysandstorm/`)
15. Space Engineers (`space_engineers/`)
16. Conan Exiles (`conanexiles/`)
17. The Forest (`theforest/`)
18. Don't Starve Together (`dontstarvetogether/`)
19. Factorio (`factorio/`)
20. TeamSpeak 3 (`teamspeak3/`)

#### Lower Priority (Legacy/Niche):
21. All remaining games in `modules/billing/docs/`

### Research Needed Per Game

For each game, research and document:

1. **All Network Ports:**
   - Game port (TCP/UDP)
   - Query port
   - RCON/Admin port
   - Voice chat ports (if applicable)
   - Steam port (if Steam-based)
   - Additional service ports (web interfaces, etc.)

2. **Startup Parameters:**
   - Command-line flags
   - Memory allocation
   - Server configuration switches
   - Performance optimization flags

3. **Common Issues (from internet research):**
   - "Server won't start" specific to that game
   - Connection problems
   - Performance/lag issues specific to game engine
   - Mod/plugin conflicts
   - Save corruption issues
   - Update/patch problems

4. **Game-Specific Configuration:**
   - Main config file locations
   - Critical settings
   - Player limits
   - World/map settings

### Documentation Template Structure

Each game's `index.php` should follow this structure:

```php
<?php
/**
 * {Game Name} Server Documentation
 */
?>

<!-- Navigation with icons -->
<div style="background: #1e3a5f...">
    <h3>📚 Quick Navigation</h3>
    <div>
        <a href="#quick-info">Quick Info</a>

        <a href="#configuration">Configuration</a>
        <a href="#parameters">⚙️ Startup Parameters</a>
        <a href="#troubleshooting">🔧 Troubleshooting</a>
        <a href="#performance">Performance</a>
    </div>
