Bookings Calendar stuck on Loading Events

Hello,

We are testing out the functionality of MS Bookings.

I've created a test site and everything was working fine yesterday.  

Today I was getting ready to demo it to our staff and when I click on Calendar it gets stuck on the Loading Events wheel.

Thank you,
