I installed the Advanced Forums (hsu_fourms) module in a new Moodle 2.7 environment. I have tested with both the "Clean" and "More" themes. When I click the "Add a new discussion" button, nothing happens. I know that with this version, an inline form is supposed to appear below that button when it is clicked. In this fairly stock Moodle 2.7 environment, I can't get it to work.
