Fix my homepage from redirecting to a mobile version

My website's homepage, [login to view URL] is loading perfectly on desktops. When I load it on my iPhone however, it tries to load a mobile version ([login to view URL]) which is a subdomain that does not actually exist. I do not want this to happen. I need someone who can figure out why this is happening (I'm guessing it's something that the hosting company is doing because I can't find any references to that "m." subdomain in the [login to view URL] of my site. All other pages on the site (those with /[login to view URL] or /[login to view URL]) load properly on the iPhone. I have all the necessicary logins to access everything. Ideally this should be a very quick job for a professional that knows what they're doing.
