Cornerstone not working. 404 Not Found openresty/1.15.8.2 error

[sparky]

Anything using cornerstone stopped working on my site. It seems to be invalid even though the main theme is valid. It was working fine until now with the validation system that was in place.

Hello @sparky,

Thanks for writing to us.

I checked your Dashboard It seems that there is some issue with your Permalink setting is not working properly. I reset your permalink setting to “Plain” and page builder started working because of the Permalink setting builder was not working. Please check the screenshot in a secure note.

I want ahead reset your permalink settings as "Post Name " and I found that Post name Permalink setting is not working properly.

The reason it’s not working is the webserver where WordPress is running is not properly configured for URL rewrite. It’s automatic on Apache’s “.htacess”, but not on NGINX server.

I found that your website is running under NGINX, which may require a different rewrite configuration. I would recommend you to please contact your hosting provider to set the WordPress rewrite configuration.
