Not sure if blogging is the right place, but I only use wordpress on my main site. I only have this one domain on this particular hosting account. So I searched google for my site, site:mysite.com and see https://mysite.com goes to another website at the top of listing. Then I tried mail.mysite.com and that goes to a totally different site too. I don't see anything in the .htaccess file. Any ideas?
