Good evening Nichole and welcome to the Events Calendar Support forum!
Thank you for reaching out to us and providing your system information.
We are sorry to hear about the calendar not displaying.
I would love to help you with this topic.
There are a couple of things you could try.
But first, go to Events -> Settings -> Display and try changing the setting for Events Template
Could you also please tell me what your event page URL is ?
Finally, if you temporarily revert back to a default WordPress theme such as twenty-fifteen, does the issue disappear ?
Let me know how that goes.
Best regards,
Geoff B.
