Herbert,

Oh. I changed it to plain.

Both headsspline and footsepline are commented out in the preamble.

Changing pagestyle from default to plain still shows the error box, with
pagestyle as default although it was changed in the saved .lyx file. Still
no page numbers. See mwe.lyx attached to my previous response.
