Hi,
ACF 5.7.9 with WP 4.8.2 and PHP 7.1.14.
1: All post/pages Preview Changes not working but if you updated it works.
2: Media does not align – Front end show it displays vertical rows top-down but at the back-end, it is arranged as side by side in the column format.
3: Custom fields text editor cannot work with Autoptmize 2.4.4. All custom fields totally not working.
