In private messages I was made aware of an issue where all users in a course were being listed in the This Course folding panel. The issue arises when you change the shortname of the default Moodle roles of "editingteacher" and "teacher". Fordson looks for these roles and will list the user details under a column titled "Teachers" so that the student can quickly message the teacher.
The fix is to change the shortname of your Editing Teacher role to editingteacher in Site Admin > Users > Define Roles. You should also change the shortname of Non-Editing Teachers to "teacher".
In the next version of Fordson I will include code that will just not display users at all if it cannot find the proper roles.
Alternatively, you can change the code of Fordson to match what you define the role of "Teacher" and Non-editing teacher.
In the core_renderer.php file find and change these two lines to match what your roles are:
$role = $DB->get_record('role', array('shortname' => 'editingteacher'));
$role = $DB->get_record('role', array('shortname' => 'teacher'));
To fix this you must change the line here to match whatever you defined your editing teacher as https://github.com/dbnschools/moodle-theme_fordson/blob/master/classes/output/core_renderer.php#L774
and non-editing teacher should be defined here:https://github.com/dbnschools/moodle-theme_fordson/blob/master/classes/output/core_renderer.php#L793
These correspond with Site Admin > Users > Define Roles. Copy and paste the "Shortname" seen in siteadmin into the code linked above.
