Trying to create a new profile to add to a Contribution Page for memberships which includes fields for username and password for Wordpress member-only content. I cannot select the User Registration or User Account checkboxes for the new profile. There is also no 'Password' type field in the Add fields screen. I have 'Anyone can register' allowed in Wordpress and have CiviCRM Wordpress Member Sync and CiviCRM Profile Sync installed. What am I missing?
