When clicking on a Process link from a Minimode version of a Process the following error is received:

You must log in to access the underlying or linked processes, please log in or contact your promaster for assistance.

Either login to the Nintex Promapp site to view this Process

Or a Promaster can change the setting Admin > Configure > Minimode > Enable viewing of underlying processes (Click through) to ON.

Processes that are unpublished will still provide an error regardless of the setting, you cannot click through to view an unpublished Nintex Promapp Process.  A minimode link for the unpublished process will need to be provided.
