I thought I was going crazy this afternoon.
Updated a client’s site to 5.7.9
All of a sudden, a date field stopped displaying the correct value.
Did some SQL queries to verify (also tried a gazillion other things.. slight hyperbole) and the postmeta values were correct.
For a given postmeta value, looking at the field in the editor, I would end up with the right one sometimes, but most of the time, it would be a totally different value.
Example: 20190207 in postmeta would display as February 9th, 2019.
Played around with the display setting… all variations would display, baiscally, 20190209.
( as an example, many of the posts had the same problem ).
I was never able to track down the problem.
However, reverting back to 5.7.5, all seems back to normal.
Unfortunately, I didn’t try more granular reverts / updates through various versions.
Sorry for not doing more testing to be able to diagnose more specifically what was going on.
What an amazing year! 🎉 ACF grew by leaps and bounds in 2018 and won't be slowing down for 2019. We have lots of new features planned, but now it is time to rest, recover, and spend valuable time with friends and family. 👨👩👧👦🎄🎁
