Pages not secure

Hi there, you are loading scripts from external URL and a logo that come with HTTP, see:

Mixed Content: The page at 'https://www.fahr-becker.nl/' was loaded over HTTPS, but requested an insecure stylesheet 'https://fonts.googleapis.com/css?family=Lato:300,400,700,900'. This request has been blocked; the content must be served over HTTPS.

This plugin doesn’t force HTTPS to the links, but rather fixing a problem that occurred on some websites that while everything was served over HTTPS (even while navigating), if you specifically tried to access a page via HTTP (via url) it won’t redirect to HTTPS.

You could also create a SSL force without a plug-in. You have only creat a .htaccess file in your website.

Install a SSL certificate at your server. I think you have this done already.
Create a .htaccess in your root file of WordPress (like domain.com/.htacces).
Put the next code into it:

# BEGIN WordPress
RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^(.*) https://%{SERVER_NAME}/$1 [R,L]
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
# END WordPress

Change your url in the general settings from https://(www).domain.com to https(www).domain.com
