404 error on event created list and even participated list...

Hello,

Something strange happen on the user events profil page :

The event created list seems to reflect reality
The event participated list does reflect the event created list...

and when you try to directly access those lists using direct url you encounter 404 error !!

see : https://screencast.com/t/dR2Vili3z


example with a user ID 77 :

user events on profil page :
https://www.rando-trekking.com/evenements/77/evenements/

user events created :
https://www.rando-trekking.com/evenements/77/evenements/crees

user events participated :
https://www.rando-trekking.com/evenements/77/evenements/aparticipe

Hope you can help
google is finding 404 error pages for the moment...

thanks in advance
Loïc
