could someone please update the webserver content reference directory to /htdocs/wordpress/

No, this is shared hosting.

The htdocs folder is NOT visible in the URL

The base of your website is linked to a htdocs folder. This means that, by default, a file name on your account matches the path coming after the htdocs part.

So if you have a file with the path htdocs/about.html, the URL will be http://example.com/about.html and the file at htdocs/images/logo.png will have the URL http://example.com/images/logo.png .

In other words, the htdocs part should NOT be included in website URLs. Unless, of course, you create an additional folder with the name htdocs within your website’s htdocs folder (so htdocs/htdocs/photo.jpg).
