Hi Boone,
Thank you for your response.
The versions of the plugins are :
– BuddyPress Docs : Version 2.2.0
– BuddyPress : Version 12.0.0
I dont’ work on the site every day, but I think the BuddyPress plugin was updated recently (maybe automatically to the v 12.0.0.). Also, the client tells me that the issue has appears just between yesterday and today.
