Hi @Jennifer
I just wanted to create a new thread and then I saw this one: https://theeventscalendar.com/support/forums/topic/months-dont-switch-at-calendar-site/
András wrote a solution which worked for me: “Please change the datepicker format to something that doesn’t contain a dot and check if that fixes it.”
Obviously you already identified the bug and hopefully you will fix it soon.
Thank you for the support
Lukas
