Course Presentation Toolbar Missing

Following a recent moodle update, the course presentation toolbar (previously located at the top of the editing box, for adding activities, images, etc.) is missing, whether in full-screen mode or not, rendering course presentation unusable. Please help.Thank you!

Please disregard the aforementioned course presentation missing toolbar problem...it has reappeared after I completely cleared my Safari history for some reason. My apologies for any wasted time this may have caused anyone.
