Hi there! I see you’re getting a “Page Not Found” error when trying to view your past and present challenges on Map My Walk. Let’s work together to get this sorted out.

To help me understand better:
- Are you experiencing this issue on the Map My Walk website, or within the app on your Mac?
- Is this happening only for your challenges page or other parts of the site/app as well?
- Have you tried any steps already, such as logging out and back in, clearing cache, or using a different browser?

Once I have these details, I can guide you through some targeted troubleshooting. Meanwhile, here are some initial steps you can try on your Mac with OS X 10.15.7:

1. Clear your browser cache and cookies — Sometimes a stale cache causes loading errors like “Page Not Found.” On Safari, you can do this by going to Safari > Preferences > Privacy > Manage Website Data, then remove data related to Map My Walk. Restart Safari afterward.

2. Try a different browser — If you normally use Safari, try Chrome or Firefox to see if the issue persists. That can help determine if it’s browser-related.

3. Check your account login status — Ensure you are logged in properly and that your profile is active. Sometimes expired sessions cause certain pages to disappear.

4. Verify your network connection — Make sure your internet connection is stable and check if any firewall or VPN on your Mac might block parts of the site.

If those don’t work, the “Page Not Found” might imply an issue on the Map My Walk servers or broken links on their end. In that case, waiting for a fix or contacting their support might be needed.

Please let me know what you’ve tried or observed, and we can move on from there! Are you ready to give these steps a try?
