Hi Shane,
I’m sorry you’re running into issues with month view…I took a look at your site, and it looks like the Tribe Bar that is typically displayed on the events page has been removed. Have you added any customizations to hide/remove it? If so, can you try adding it back and see if you are then able to change to month view? Can you also send me a screenshot of your settings under Events > Settings > Display > Enable event views?
To try and improve performance for month view, I would recommend taking a look at the following articles:
Performance issues are typically caused by a variety of factors and may require several steps to see a difference, but the articles above have some good tips on ways that you can improve performance.
Let me know how it goes!
Thanks,
Jennifer
