It looks like that fixed it. Many thanks!

Contents of the root .htaccess file (with website replaced by “domain”

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

# Redirect non-www urls to www
RewriteEngine on
RewriteCond %{HTTP_HOST} !^www\.domain\.com
RewriteRule (.*) https://www.domain.com/$1 [R=301,L]

I have not created a network. I have never used a network for this type of install before. Is this a new requirement for WP? I’ve run up to 8 sites on one domain in the past without setting up any networks.

Any tips on this would be appreciated.
