To summarize, it seemed that if I deleted and replaced both Modules - Timeline and Protean - with no customization - it would surely be OK. So I did. But the original problem exists in the Protean timeline on the home page of the site.
Things are fine in the Ocean 10 Template.
Also, is there anyway to make the Timeline entries (cards) to re-populate? I am not certain if they were deleted because I do not know where they were stored. Do you? :) I did not see it in the big storage folder - only Timeline photos.
Help me if you can. Thank you. And special thanks to Chris who has gone far beyond the call of duty to look into this strange issue.
