🐛 Troubleshooting

Common Issues

Issue: Components not loading Solution: Check database connection and verify components table has data

Issue: CSS/JS not loading Solution: Verify file paths in Smarty template match actual files

Issue: Can't save templates Solution: Check user authentication and database permissions

Issue: Drag-and-drop not working Solution: Ensure JavaScript is enabled and browser is modern

Debug Mode

Enable logging in PHP:

error_reporting(E_ALL);
ini_set('display_errors', 1);

Check browser console for JavaScript errors.
