If I click on the 'By Month' filter, my events page switches to the month view. So far, so good.... I then click the forward month arrow on the main panel header to move to January 2017... so far, so good.
This gives me a URL like mysite.com /events/date/2017-01
I'm trying to send this to a user but when they load that URL it loads 2016 data.
On further testing if I do any month in 2017, it drops back a year... so mysite.com /events/date/2017-04 loads April 2016 data.
Also I notice if I put this URL in my browser: mysite.com /events/date/2016-12 then the 'forward' arrow to the right of the main panel month header then tries to load /events/date/2016-13 instead of /2017-01
