I have the same problem.
I use the most recent versions of WP, BP and the courseware plugin.
The lecture view gives a correct and working link when using the artikel plugin, but the link-plugin doen't show up when puted in the template
buddypress-courseware/groups/templates/single_lecture.php
At the bottom
ID ); ?>
The problem with the artikel-mode is that on assignment Quiz, it places a link on every selection.
Other simular plugins working in a simular way, work when placing the link on that place. Yet I would like to use PDF24 as it is the best there is. It is a lot better in creating the PDF an the workaround options.
Any help would be great
