it’s weird : in case of posts number on this “page 2” is < “15” the theme selected is the mobile theme, even if not on mobile (Safari, Chrome and Firefox tested). If post number>15 the theme is full site.
More of that : this issue occurs ONLY if the visitor is NOT logged. If logged, everything is fine.
Any idea about this ? It’s annoying because all visitors not logged going to a topic’s last page see the mobile theme.
