Hello all and sorry for the delay… I had to spend quiet a lot of time in order to figure it all out before applying the changes to a productive site.
I proceeded as Gary suggested and I found the culprit. It was the extension “Huge IT Lightbox” that prevented Baskerville from displaying the articles unless it was on a mobile display. One does encounter strange phenomenons from time to time ?? Once removed, everything works like a charm !
A big thx to you all and – happy Easter !!
