I haven’t yet found it but I’m narrowing it. I can order at will the pages of the exercise, using the CMS. And with 4 or 5 pages, it is always the second page that displays on the right, whatever page it is.
So, it must come from some css property the CMS outputs in there. But I could not find which one yet.
God ! Now, the issue is solved. What happened ?! I had just removed from the Exercise 2 page, the introduction text, and then copied it back from the Exercise 4 page. It is an exact copy of the text. In fact, this text is html markup. I wondered if it could have been the reason for this. Removing it from the page did not solve the issue though. Only copying back into the page, from an exact copy sitting on another page, and having things as they were at the start, solved the issue. I don’t know what was happening here. Sorry guys. I wish I had caught it in the act. High chaparal…
