## 🛠️ Troubleshooting

### Events Not Displaying

**Check 1**: Clear cache
- Admin → Calendar Management
- Click **🗑️ Clear Cache**
- Confirm and refresh page

**Check 2**: File permissions
```bash
ls -la data/meta/calendar/
# Should show www-data:www-data ownership
# Should show 775 permissions

# Fix if needed:
chown -R www-data:www-data data/meta/calendar/
chmod -R 775 data/meta/calendar/
```

**Check 3**: Check JSON validity
```bash
cat data/meta/calendar/2026-02.json
# Should be valid JSON
# Check for syntax errors
```

### Color Bars Not Showing

**Symptom**: No colored bars in clicked day events

**Solution**: 
1. Clear browser cache (Ctrl+Shift+R)
2. Clear DokuWiki cache (admin button)
3. Check browser console for errors
4. Verify plugin version is 3.10.6+

### Tooltips Not Working

**Symptom**: Hover over system bars shows no tooltip

**Solution**:
1. Verify JavaScript is enabled
2. Clear cache
3. Check console for "showTooltip_sidebar_* is not defined"
4. Update to version 3.10.6+

### Weather Shows "--°"

**Solution**:
1. Clear cache
2. Allow geolocation in browser (or uses Irvine, CA default)
3. Wait 10 seconds for initial update
4. Check console for weather API errors

### Outlook Sync Not Working

**Check 1**: Azure credentials
- Verify Tenant ID, Client ID, Client Secret
- Check app permissions in Azure Portal
- Ensure admin consent granted

**Check 2**: Sync logs
- Check `/lib/plugins/calendar/sync.log`
- Look for authentication errors
- Verify API call responses

**Check 3**: Cron job
```bash
# Check cron is running
crontab -l

# Should show:
*/15 * * * * /usr/bin/php /path/to/dokuwiki/lib/plugins/calendar/sync_outlook.php
```

### HTML Formatting Not Rendering

**Symptom**: Event shows `**bold**` instead of **bold**

**Solution**:
1. Clear cache (critical!)
2. Verify DokuWiki parser is working
3. Check `title_html` and `description_html` fields exist in JSON
4. Update to version 3.10.2+

## 📊 Performance

### Optimizations

- **Event Caching**: JSON files cached per month
- **Lazy Loading**: Events loaded on demand

- **Events per month**: < 500 (no performance issues)
- **Events per day**: < 50 (UI remains clean)
- **Namespaces**: Unlimited (loaded separately)
- **Event description**: < 500 characters (for readability)
