I do not use CloudFlare, but I went through and deactivated everything, and tried running only the calendar, and still nothing.
I was looking over on http://tri.be/support/forums/topic/calendar-pagination-link-for-2014-02-not-working-correctly/ and saw that a lot of other people were having problems late last year, when we weren't having problems, but I want to say since the last update is when I noticed it.
It works for me in Internet Explorer, but neither Firefox or Chrome. The only way it works is if I refresh the page, but my users are not going to know that. :( The URL changes to the correct month, but moving it back or forward keeps it on the current month, or if I type in a URL for the next month, it'll work, but if I try to go forward with the navigation, it goes back to the current month.
Thanks for your help.
