Update: problem identified, workaround in place
On a hunch, I deleted the two video fields which fetched videos from Youtube. Problem solved!
There was NOTHING to indicate the problem came from them. The links to the videos were set up in a Product field, appearing as links like this one:
https://www.youtube.com/watch?v=4GIk2Bp3FcA
and these links all worked perfectly. But as soon as I deleted them from the Products, and removed all reference to them from the template that controlled how they appeared online, the Warning messages vanished. Go figure!
The product pages now look fine (see this example: https://rolanditen.com/product/r8-mark-ii-sport-stainless-steel-red-gold/) but of course there are no more videos. On balance I think the client will prefer this to bug-causing video links; I’ll be informing them shortly.
Any idea, John, what has happened between Youtube and ACF to create this phenomenon?
Many thanks for your work so far, anyway.
