When you entered an e-mail address for your wife, you invited her to join WikiTree. From the e-mail she received from WikiTree, follow the instructions to make her a family member on WikiTree. 'She' will have to change her own privacy level and/or she can add you to her trusted list. If that doesn't work, send an e-mail to info@wikitree.com, explain the situation, including your relationship to her, and ask them to remove her e-mail address and invitation and turn her profile back to you as profile manager.
