I used the User Meta Pro plugin to export users and their extra checkbox fields (created by user meta plugin) and then I tried to import to another site to create the users and their specific checkbox values. The users import ok but the checkbox fields do not get loaded. Text fields work ok but not checkbox fields. Registration date field and email are also not coming over and they are standard fields.
You might not be using the “User Export” setup correctly.
Make sure to assign a field for each column data.
If a field is not a default WP field, please choose “Custom Field” as the “Assigning Field” and make sure there is a meta name given under that.
