Hi,
Sorry for the issues you are having.
I see what you mean. The list view works, but the Month view looks to be producing an error and a white screen.
Please follow our testing for conflicts guide:

And see if that resolves the issue.
Also, I would look into your php error logs or turn on debug in your wp-config.php and see if that shows any errors that might cause this.
Here is a link for the WordPress debug:

Let me know what you find out and we can go from here.
Thanks
