Hi all, we’re experiencing same issues as welswebmaster. WPEngine, PHP 7, large site, 502 errors, heavy autoload, same results with or without object caching or parent/child theme. We do not experience these issues with Enfold 4.2.6. We have not found a solution for 4.3.x versions.
This client is a high value eCommerce site, very eagerly anticipating new options/suggestions for resolution.
Thanks in advance Basilis and Kriesi crew!
