Inaccessible Blog after Upgrade

If your blog is at https://www.denacrain.com/blog, then looks like you got the problem solved.

On another topic, if you want to make your blog appear at https://www.denacrain.com with very little effort:

1. Delete whatever mechanism (some index file) is now redirecting visitors
2. Change, in Settings-General, the Blog address (URL) to https://www.denacrain.com, and put this index.php file in your web-root folder (it is the same folder that contains the blog folder)

<?php
/* Short and sweet */
define('WP_USE_THEMES', true);
require('./blog/wp-blog-header.php');
?>

Then update your permalinks in Settings-Permalinks.

I see now that it is working; perhaps it was a problem with my browser. Thanks very much, Michael, though, for the prompt reply and for the pointer on redirecting my links. That’s another problem, set up for me by a third party, that has been bothering me. I’ll take care of it asap.
