The issue is with Sermons, & Church hero the app we use for our sermons, not with MEC.
We create a new sermon to be entered into our Sermon page. See Screenshot 1 which shows the date chosen as May 3rd. Church Hero has the date above the calendar showing as YYYY/MM/DD which has always been the format there (for several years). Screenshot 2 shows how the date chosen (May 3rd) is NOW displayed on our Sermon page as March 5th - so it has changed to a mm/dd/yy format whereas until recently(last month or so), it displayed as it should have dd/mm/yy. Up until month ago approx. that would have read May 03 2020.
In Screenshot 3, the calendar date chosen is May 25 2020. This is now displayed on our sermon page Screenshot 4 with a date called Undefined because the day date (25th) is being read as a month date or a month number & there is no 25th month, so the page reads a date as Undefined.
Church Hero has not updated anything on their app for over a year. So, nothing has changed with with Church hero to cause these changes with dates in the last month (approx.) The only things that have changed in the last month os so that I can see could cause this problem is changes with MacOS & also changes with your Theme.
Again, this date issue DOES NOT show up on earlier versions of MacOS, It DOES NOT show up on Firefox. It DOES NOT show up on Windows computers. Everything works as its should (the dates display correctly) on Macs running older versions of the operating system. Everything works as its should (the dates display correctly) on computers running Firefox (on a Mac). Everything works as its should (the dates display correctly) on Windows computers.
The problem exists (the dates DON’T display as they should) on computers running the latest MacOS or on computers running Google Chrome on a Mac.!
