A new change has caused an issue with HHVM. I’ve been using HHVM on my sites for about 2 years and always ran well. The recent update is causing a 502 error on a certain page. Using more than 1 content area. But on 7.1 it loads fine.
I also got error on HHVM.
ACF pro cannot loop correctly on HHVM.
And its load is really heavy.
Switched to php-fpm7 then it was resolved.
