Use .htaccess to redirect HTTP to HTTPs

Question

With my current .htaccess, this is what happens:

https://www.dukescasino.com/ - works perfectly

https://dukescasino.com/ - redirects to the above which is great

The two options below loads fine, but it should be redirecting to the https version:

http://www.dukescasino.com/

http://dukescasino.com/

Here is the current .htaccess:

<IfModule mod_rewrite.c>

RewriteEngine On

RewriteBase /

# BEGIN WordPress

RewriteRule ^index\.php$ - [L]

RewriteCond %{REQUEST_FILENAME} !-f

RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule . /index.php [L]

</IfModule>

I don't believe it is relevant, but if so, here is the list of current active plugins:

• Advanced Custom Fields

• All In One SEO Pack

• Bop Search Box Item Type For Nav Menus

• Contact Form 7

• Disable Comments

• Google XML Sitemaps

• Jetpack by WordPress.com

• Search & Filter

• Slider WD

• TablePress

• UpdraftPlus - Backup/Restore

• Wordfence Security

• WPide

• WP Smush

• WP Super Cache

Result: 302 found. Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request

To get rid of the error you can use the below mentioned code:-
