First of all thanks for the great work, happy to study this promising subject. Also nice to read about minimalist ideas. I sure hope I’ll help keep up the good work (and get a cold beer !).
Regarding the plugin, I tried to apply it to my site but ran into en error.
Sorry if I overlooked something, but this is what I get :
404 error code returned from server. Please check your server's error logs or try increasing your max_execution_time limit in PHP if this consistently fails after the same duration. More information of the error may be logged in your browser's console
Not a Console expert but I see this in Dev tools:
Failed to load resource: the server responded with a status of 404 () /wp-admin/admin-ajax.php:1
Currently on a shared server so I cannot change memory limits. Any hint ?
