I've tried with 2 x installations of V2.3 and I can't get my lessons to be presented as a slideshow.
The lessons have all been created inside moodle and are only using content pages. I followed the guide at http://docs.moodle.org/23/en/Lesson_settings
I read elsewhere that the powerpoint import for lessons has been removed from V2.3 as it doesn't work so I'm wondering if that is the reason why I can't get my lessons to be presented as a slideshow. Perhaps there is some relationship.
Has anyone else got lessons running using the slideshow option in V2.3
Many thanks in advance.
