How to edit the .htaccess file to redirect from HTTP to HTTPS for WordPress sites using SSL

In the .htaccess file found in the root folder of your WordPress site, add the following lines:

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

Make sure to add them before the line that says # BEGIN WordPress. WordPress will remove any lines that you add in between the lines # BEGIN WordPress and # END WordPress when you flush the permalinks. So for example, your complete .htaccess file should look something like this:

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

# 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
