What’s the domain?

www.saledji.com
Sometimes parse to saledji.com.
saledji.com is not my website.

That site is working fine from here. When did you add the domain to the account? If it’s less than three days ago, you may need to wait for DNS to propagate.

Just three days, I was waiting for the next try. Thank you!
