Problem is with all the settings for that role stick
I’m using Extension “User Role Editor”, Version 3.12.1 (latest)
NB: “participant” is a secondary role within wordpress/bbpress, I’m surprise to found it in the role list proposed by Events Manager.
“Participant” means that the user is allowed to participate to the bbPress forums. But it says nothing about role in the multiste blogs.
I think the Events Manager is confused with “Participant”. It should ignore the secondary role and use only the primary role.
It seems I have an issue with members registered in the multisite, without any primary role (blog access is read only) and with “Participant” secondary role (bbPress).
Found in the “User Role Editor” forum : By default WordPress assigns only one role to the user. BBPress started to use multi-role feature: it assigns more than 1 role to the user at once and does that on the fly.
Says otherwise, Events Manager seems incompatible with the way wordpress/BBPress is managing multi-roles.
