Troubleshooting Tips

Can’t advance to pre- or post-lesson checks? Please update your computer to requirements above.

EZIZ lessons require all buttons clicked, questions answered, and audio finished before proceeding to the next page. Please click any buttons or photos according to the instructions.

If the Next button still does not work, these are the two most common problems:

Issue: A glitch occurred during page loading.

Solution: Delete your browser history (temporary internet files/cache/history), exit all browser windows, and access the lesson again. (Follow these instructions for deleting temporary internet files for Microsoft Edge and Chrome.)

Issue: Your computer is behind a content filtering system that blocks you from accessing certain websites (e.g., entertainment or game websites).

Solution: Request that your IT department whitelist “eziz.org” and “lms.eziz.org”. This will ensure that no files are being restricted from loading.
