Thank you Steve
Yes, it’s one table in my database.
It looks exactly like what is described in the article you found. I’ll try it.
The problem only occurs with my iPhone. When I go to the homepage of my blog and clic on that article’s link, I land on a page that’s not my article. But the URL is still the correct one.
If I do the same on a PC (ie go to the homepage and click on the link), I land on my article.
Thanks that solved the problem.
