This is where you would put domain redirects if need be. So you may need to personalize it but here’s the base from which to start. Just copy below and paste it into your htaccess file.
# BEGIN WordPress
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
# END WordPress
# Turn off index browsing so directories with no index files will not display the list of files
Options -Indexes
# Deny browser access to these files – these should always be denied to the public
# wp-config.php, wp-config-sample.php, bb-config.php, php.ini, php5.ini, readme.html, license.txt
Order allow,deny
Deny from all
# Turn off server signature information from hackers
ServerSignature Off
# Deny browser access to protected server files – .htaccess, .htpasswd and all file names starting with dot
