can't invite new user to group
User Pat Laurence created a commons account using her email email@example.com. Her username is briscoe (https://commons.gc.cuny.edu/wp-admin/users.php?s=briscoe&action=-1&new_role&bbp-new-role&bbp-bulk-users-nonce=53f8097c5f&paged=1&action2=-1&new_role2&bbp-new-role2)
I am trying to invite her to this groups - https://commons.gc.cuny.edu/groups/poets-together/ - but the invite modal won't populate her username, and using the email sparks an error.
What should I do?
Is this happening because the group was created before the username?
Thanks for any clues!
