404 Errors

After installing The Events Calendar, the calendar slug isn’t working- I get a 404 error.

I tried changing the calendar slug from calendar to something else and it didn’t work. I do have a page called “calendar” so I tried removing that page and still nothing.

I tried disabling all of my plugins and setting my theme back to 2013 and the permalink still doesn’t seem to be working.

I went to settings/permalinks and clicked the save button to update permalinks and still nothing.

WP Debug Bar has a section for “tribe” and it shows:
tribe_version_test commands
Array
(
[0] => get wordpress
[1] => get php
)

Is there anything else that I can try to get the calendar up and running?
