[CoursePress Pro] CoursePress Pro Theme not displaying course content

I have previously developed a childtheme for the CoursePress Theme which was in use on this site and was working until recently. since WP 5.0 the site has stopped displaying the course contents on either the Child Theme (sophia LMS) or the parent theme CoursePress.

As a stopgap measure I have reverted to Tweny Nineteen but that obvously means all styling on the site has been lost.

Could you have a look at the Parent Theme and let me know what is causing this issue>?

I have tried updating to the latest release of the CoursePress pluginm but that doesn't seem to fix the issue and I suspect has not updated the Theme file anyway (thus creating more incompatibilities).
