"Your request can not be completed. Please login and confirm the invitation manually"

When sending an invitation to join a hidden group to alredy registered users (seems working fine with not registered), the text message is not added to email notification and the link to join the group causes the error: "Your request can not be completed. Please login and confirm the invitation manually"
Also tried to logout and then opening the link, same error.
Using Hypeinvite 1.0.3 and Elgg 2.3.2
Cheers

Actually, the user gets added to the group but that error persists and misleads. Also, the group's welcome message (from Group Tools by ColdTrick I guess) doesn't get sent. Maybe some incompatibility

If useful, todayìs error log:
