Youtube comments do not load in Safari 13.0.4 on High Sierra

Thank you! One of the suggestions here worked. Maybe I missed it or ignored in other discussions. Here's the fix:

. . . remove data related to that site to see if it fixes the issue. Use these steps to remove cookies, cache, and other data stored by Safari for a specific site:

1. 1. Choose Safari > Preferences.
   2. Click the Privacy icon.
   3. Click the Details button.
   4. Search for the name or domain of the website whose data you want to remove.
   5. In the results list, click the domain (like example.com) that has data you want to remove.
   6. Click Remove.
   7. When you're finished, click Done and close the preferences window.

While I was at it, I deleted all the listed sites because I didn't recognize any of them.

Since it worked on the desktop iMac, I assume it's going to work on the Air. If not, I'll be back.

Thank you again.
