I used to create, on my test site (www.fguelat.ch) a category menu bar with a category called "news from the community" where I could display all published news. It worked perfectly the way I wanted
Now I switched into production mode with a new URL (www.humanitarian-psy.org) and I got this message: Not Found, Sorry, but you are looking for something that isn't here when I click on the same button "news from the community"
If I look at the breadcrumb navigation on my test side, I can see that the path looks like this:
Home > Archive by category 'News from the community'. I've checked both sites in admin mode many times but I miss something.
Can someone help me? Many many thanks in advance
