I got it : I’ve been tricked cause I set the menu with the buddypress items and not from the page menu. I guess that was what you were saying but maybe my poor english forbade me to understand.
As you say, a sorting blip. You learned to me those words. I will remember them : they cost me two full days of pain !

Thanks anyhow !

Same in buddypress page setting : all pages exist and are linked correctly.
So practically, Buddypress tabs link to htttp://DOMAIN.LTD/members/my-account/activity and cannot access to the base directory through the url http://DOMAIN.TLD/members/

No; absolutely not. You did not reach the point : on the menu tab, indeed I can see a buddypress tab under the pages. That the links I use. But those items link by default to MY USER’s directories (activities, friends, groups, agenda) and not to the base directory as it is supposed to do.
You get it ?

I’d appreciate to get an answer. Until the landing page is not usable, my site cannot be effective.

I repeat : I’ve been following your instructions. That didn’t worK.

Events Manager plugin is not showing off neither. Could it be connected ?

This is exactly what I did… and what didn’t worked. Any ideas ?
