404 when receiving an invitation to group

I’m using invite anyone together with buddypress, both updated. When I send invitations to groups, users come back to me saying they only see an error 404 message.

I deactivated invite anyone and invited from buddypress and it works fine, but we don’t want the friend request option in our web.

I can see that the url that is giving 404 is the same as the one created with buddypress /members/test/groups/invites/?n=1

Any way to solve this?
