  • You find an "Unexpected error occurred" message during a Copy page action.
  • Checking the logs there is a trace like this:

  • All Liferay Portal and DXP versions


  • The user performing the action must have the ADD TO PAGE permission for every portlet/widget in the page.

  • Check your Roles configuration and be sure that the user has a Role containing these permissions, normally the User role is the default for this purpose but it could be other based on your requirements.
