Test not loading or displaying correctly

If a test isn't loading or displaying correctly:

1. Check your internet connection — a stable connection is needed to load and save test responses.
2. Enable JavaScript — NOESIS requires JavaScript (enabled by default in all modern browsers).
3. Try a different browser — we support Chrome, Firefox, Safari, and Edge (version 90+).
4. Clear your browser cache — outdated cached files can sometimes cause display issues.
5. Disable browser extensions — ad blockers or privacy extensions may interfere with page loading.

If the test page loads but questions aren't appearing, try refreshing the page. Your progress is auto-saved, so you won't lose any answers you've already given.

If the problem persists after trying these steps, please contact us with your browser name and version so we can investigate.
