I am using a Wordpress site with an installed SSL certificate. When accessing the site, it shows that the connection is "Not secure". When clicking on the "Not secure" tab, it shows that the certificate is installed but no further information. Only when accessing the Wordpress wp-admin dashboard, it shows that the connection is secure.
Why does it not show that the connection is secure when accessing the main website? What do I need to do to show that the connection is secure?
