I've been using v4.0.1 of the booking calendar without any issue and after upgrading to v4.1, v4.1.1 and v4.1.2 I'm no longer able to select days in the calendar. I've cleared my browser cache, tried different browsers and PC's and it no longer works. I've revert back to v 4.0.1 and the calendar works. I then upgrade back to the latest v4.1.2 and I get the same fault again.
I've now reverted to v4.0.1 again and evrything works fine. Any idea why this happens?
