I am also facing the same issue as @nicholas_turbanov .
Hello,
Wordpress version – 4.9.7
ACF Pro version – 5.7.1
PHP Version 7.2.7
Problem –
1) ACF works well in localhost Apache server.
2) When moved to Nginix server and after ACF fields sync, the location rule for the field group is manually updated to a page (For example homepage).
3) Check the homepage screen where the location rule was supposed to be affected, the field group will not be present/visible in that page.
4) I don’t get any errors in the console and cannot replicate this issue on my localhost.
This happens only when run on Nginx server.
