My clean install of Wordpress is responding with a 404 at /wp-json.
The URL I'm using is temporary in the format http://111.222.333.444/~account/
I can access the blog at http://111.222.333.444/~account and wp-admin at 111.222.333.444/~account/wp-admin. I can't access wp-json at 111.222.333.444/~account/wp-json/
I've tried both Wordpress 4.7.5 and 4.7.4. I've installed through Installatron (4.7.5 and 4.7.4) and Softalicious (4.7.5 only) and neither work.
My host uses a LiteSpeed server. There are no .htaccess files in obvious directories. I am using the same host for another Wordpress instance (also 4.7.5) and its /wp-json/ works fine.
On one install attempt, /wp-json/ responded with the blog home page rather than a 404.
I have tried inserting index.php in the URL (i.e. 111.222.333.444/~account/index.php/wp-json
... and I've run out of ideas. Any help, please?
