Hey,
I have a big issue which I cannot get solved:
Everytime when I start editing a page with cornerstone, the server goes down.
The first few changes are shown in the live preview. The next ones not. The console gives me these error messages:
POST https://mydomain.com/cornerstone-endpoint 500
POST https://mydomain.com/wp-admin/admin-ajax.php 503
I already cleared my cache, disabled caching plugins but nothing helped yet… Any idea what this could be?
