LearnDash Quiz Not Saving: Troubleshooting Guide
Experiencing issues with LearnDash quizzes not saving progress? This can be incredibly frustrating for both students and administrators. Here's a breakdown of common causes and practical solutions to get things back on track.
Common Causes and Solutions
Several factors can contribute to LearnDash quiz saving problems. Here's a checklist to help you diagnose and fix the issue:
- Plugin Conflicts: Deactivate all plugins except LearnDash and its core add-ons. Test the quiz again. If it saves correctly, reactivate your plugins one by one, testing after each activation, to identify the culprit. This is often the #1 cause.
- Caching Issues: Caching plugins can sometimes interfere with session data. Clear your website cache and browser cache. Try the quiz in a private browsing window (Incognito mode) to bypass cached data entirely.
- LearnDash Version: Ensure you are running the latest version of LearnDash. Outdated versions can contain bugs that have been resolved in newer releases. Check for updates in your WordPress admin panel under "Plugins".
- PHP Version: LearnDash requires a minimum PHP version of 7.2. Ideally, you should be using PHP 7.4 or higher for optimal performance and security. You can check your PHP version within your hosting account's control panel.
- Server Limitations: Low PHP memory limits can prevent quizzes from saving, especially if they contain many questions or media. Contact your hosting provider and request an increase to the PHP memory limit. A minimum of 256MB is recommended.
Advanced Troubleshooting Steps
If the basic troubleshooting steps haven't resolved the issue, consider these more advanced solutions:
- Database Issues: Run a database optimization plugin to clean up your database and remove any orphaned data. Plugins like WP-Optimize can help with this.
- Theme Conflicts: Temporarily switch to a default WordPress theme (e.g., Twenty Twenty-Three) to rule out theme-related conflicts. If the quiz saves correctly with the default theme, the issue lies within your original theme.
- Review LearnDash Settings: Double-check your LearnDash quiz settings, specifically the "Save Progress" option. Ensure it's enabled. You can find this setting within the quiz's edit screen.
- Contact LearnDash Support: If all else fails, reach out to LearnDash support for assistance. Provide them with detailed information about the issue, including the steps you've already taken to troubleshoot it.
By systematically working through these steps, you should be able to identify and resolve the issue preventing your LearnDash quizzes from saving.
