Thanks, guys! I found the .htaccess file. Saved the existing version as a backup, and replaced this code:

RewriteEngine On
RewriteBase /

with

RewriteEngine on
RewriteCond %{HTTP_HOST} !^www.beadinspirations.com$
RewriteRule ^(.*)$ http://www.beadinspirations.com/$1 [R=301]

Saved it and uploaded it. It seems to have fixed the problem.
