Much thanks, Gentlemen! This is quite interesting. I am learning many things.

Your solutions will benefit others, too.

When the page began to work again with the Timeline, I thought (mistakenly) it may have been a Cloudflare cache issue - which can actually be regional.

When Leonid first examined the home-page on the other side of the world, it only displayed a certificate error with no UNA content at all. This SSL issue had been fixed 2 days prior.

Cloudflare has a Developer option to turn it off. But this does not flush the cache. Many have reported that the Cloudflare cache gets corrupted on rare occasions.

The part which amazes me is how certain boxes became unchecked regarding who had permission to view the Timeline. This has occurred twice in the last month. I have now changed this Timeline "view" setting to: ANYONE.

But these issues were not the real problem...
