One page on my website does not work if i do not put www. in front
I am using Apache virtual hosts on ubuntu 14.04 64 bit on a 512MB droplet. I have 3 very small sites setup right now. I have set up the main site to always go to www.domain.com even if you type in domain.com using .htaccess file. Another site i am hosting (www.sheardlitearabians.com) does not seem to follow the .htaccess file, and you can access it using the preceding www or without.
My real issue is if you go to the site with the site is if you go to it sans www, and click on sales, for some reason it puts the www. in front and puts the slash that is supposed to go in front of sales, behind it! ex: http://www.sheardlitearabians.comsales.html/
i downloaded this site from my previous shared host.
any idea what's going on here??
