Tell us what you are trying to do?
I am trying to use the plugin Events Calendar by Modern Tribe. It displays the calendar now, but not any events. There should be one on March 14th this month. Here are the links where it's being used: hidden link & hidden link
Is there any documentation that you are following?
No.
Is there a similar example that we can see?
Here is a link to another site using the plugin: hidden link & hidden link
The events post type is created by the Events Calendar plugin and it normally handles displaying the events archive as a calendar, as well as single events.
How have you involved Toolset in this?
You don't appear to have created a custom events archive as the normal plugin calendar is showing. Did you make a content template to display single events? Did you include fields in the template, including the post body, and other fields you want to appear?
For the events archive displayed on a calendar I suggest you temporarily disable Views if you have it active to see if it affects anything. (Views has a small integration layer with the Events Calendar to prevent it overriding Views queries of the event post type to only show future events, which is the default.)
If you have created a Content Template for single events, check that you included content in that template.
