kjoymarcotte on "Host name mismatch"

Hi,
I created a test site to learn wordpress. I called it:
http://www.hearttotheartlomilomi.wordpress.com. Note the typo. It should be: http://www.hearttoheartlomilomi.wordpress.com. When I was ready to launch my website, I registered http://www.hearttoheartlomilomi.com and linked it to my test site.
Now Safari puts up a security warning about the certificate for my site, saying: "This certificate is not valid (host name mismatch)".
I think this must be because my test site has a typo in it so they don't match. Does anyone know how to fix this problem?
Thanks
Joy
