I installed the beta and can confirm that after changing the settings back to site default the calendar now displays the correct month.
Cheers.
Hi Nick,
Oddly, i’d already tried toggling between site default (it’s original setting that had worked for about a year) and event source, without success. I hadn’t tried custom but find that it does indeed fix my problem. I now get the correct month, thanks for the suggestion.
I’m also getting exactly the same issue, WP 4.6.1 and Simple Calendar 3.1.6
