Hi there! I understand you're having trouble navigating within the Surfline website. Could you tell me a bit more about what's happening? For example, are links not responding, pages not loading, or are you unable to see menus or buttons? Any details you provide will help me guide you better.

In the meantime, since you’re using macOS 10.15.7, let's try some initial steps that often help with website navigation issues:

1. Refresh the Page: Sometimes a simple reload (Cmd + R) can fix temporary glitches.

2. Clear Browser Cache: Cached data can sometimes interfere with interactive elements. You can clear the cache in your browser's settings. If you're using Safari, go to Safari > Preferences > Privacy > Manage Website Data > Remove All.

3. Try a Different Browser: If you’re using Safari, try opening Surfline in Chrome or Firefox to check if the issue is browser-specific.

4. Disable Browser Extensions: Some extensions can block scripts necessary for navigation. Temporarily disable them and check the site again.

Let me know if you’ve already tried any of these or if the problem persists after trying them. Then we can look deeper, including checking for any known issues with the Surfline site or your account.
