URGENT - EVENTS+ Pages GONE ODD!

HI

My two EVENT pages that I spent MONTHS working on to get working and have been fine for the past 6 months or so are NOW VERY ODD (was it a recent update???)

1. https://www.publicaffairsjobs.com.au/learning-centre/training-calendar/

This is now a blank page - it was a calendar WITH SIDEBAR.

2. https://www.publicaffairsjobs.com.au/learning-centre/events/

Instead of a LIST of EVENTS, this is now showing as the CALENDAR WITHOUT a SIDEBAR.

WHAT IS GOING ON PLEASE?

I NEED TO FIX ASAP SO PEOPLE CAN BOOK INTO OUR COURSES RUNNING NEXT WEEK!

Thank you.
