We can redirect our Prestashop from www to non-www or vice versa. To do this, we must access the folder that contains the Prestashop either through FTP or Plesk and edit the .htaccess file.
Redirect www to non-www:
Find:
Add below:
RewriteCond %{HTTP_HOST} ^www.yourdomain.com$ [NC]RewriteRule ^(.*)$ http://yourdomain.com/$1 [R=301,L]Redirect non-www to www:
Find:
RewriteEngine On
Add below:
RewriteCond %{HTTP_HOST} ^yourdomain.com$ [NC]RewriteRule ^(.*)$ http://www.yourdomain.com/$1 [R=301,L]Remember that if you regenerate the htaccess from Prestashop, these changes will be lost and you will have to redo them.
