Hmm, since I’m here, I’m a bit puzzled as the topic doesn’t appear in its own category:
Here’s the topic: Monocycle.info fait peau neuve - Actualités - Monocycle.info
Last activity June 19, but I can’t find it here: Actualités - Monocycle.info
Why doesn’t it work on this very topic then? Why doesn’t rebuilding the HTML work? 
Maybe it’s a server-side cache issue?
