Problems in redirecting to HTTPS

Hello,

I am using latest version of your plugin and WordPress.

There seems to be only one problem, all other versions of my website are redirecting to the one I want but there is one version which is not, I mean:

The actual URL of my website is https://www.onlinecasinowarrior.com

Now:

http://onlinecasinowarrior.com is redirecting to https://www.onlinecasinowarrior.com

https://onlinecasinowarrior.com is also redirecting to https://www.onlinecasinowarrior.com

BUT

http://www.onlinecasinowarrior.com is not redirecting to the actual link.

MY really simple SSL configuration :
Everything is checked except for “Enable javascript redirection to ssl” and “Stop editing .htaccess file”.

My current htaccess file looks like:

# Force to WWW
RewriteCond %{HTTP_HOST} !^www\.(.*)$ [NC]
RewriteRule ^(.*)$ https://www.%{HTTP_HOST}/$1 [R=301,L]

# BEGIN WPSuperCache

# END WPSuperCache

# BEGIN rlrssslReallySimpleSSL rsssl_version[2.5.13]
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
</IfModule>
# END rlrssslReallySimpleSSL
# 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
