The PublishPress Capabilities plugin allows you add permissions that might not be available on your site currently.

In this example, I'm adding the erase_others_personal_data permission.

  • After installing PublishPress Capabilities, go to “Capabilities” in the WordPress admin menu.
  • In the top-left corner, choose the role you want to edit.
  • In the “Add a New Capability” box, enter erase_others_personal_data.
  • Click “Add to role”.
  • Look in the “Additional Capabilities” area and you'll see your new permission. In this case, the box says “erase others personal data”.
