Hallo CBaumi02,
in der .htaccess Datei im Shoprootverzeichnis musst du folgenden Code
##-- redirect to https www-domain, when www is missing and no subdomain given and not using an ssl-proxy
#RewriteCond %{HTTP_HOST} !^www\. [NC]
#RewriteCond %{HTTP_HOST} !\.(.*)\. [NC]
#RewriteCond %{HTTP_HOST} !^localhost [NC]
#RewriteRule ^ https://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
#RewriteCond %{SERVER_PORT} !^443$
#RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
durch diesen Code ersetzen.
