Some issue with line with www. and without

[timlo]

I am doing on a website www.engravegift.com

and I have found it when I typed with the address with www and without www , the heading of the homepage or other page will be slight different.
like the menu icon isnt displayed corrected, and when it loggin in, the welcome back customer will show when with www. and not show with not www.

Hello

You can configure .htaccess file to redirect automaticly all users if they visit non www version
Something like this http://www.inmotionhosting.com/support/website/htaccess/force-www-htaccess
