Want to use own Domain name without getting directed to website.000webshot.com

Hi,
Im new with building a website. I looked up so many tutorials and still it doesnt work. Can Someone please help me?

I set the name servers NS01.000WEBHOST.COM and they are working.
The only thing is, when I enter my website: www.hurinuku.com now, it gets directed to the 000webhost.com website.

Also, when I change the website in wordpress, my website becomes insecure and I cant login anymore in wp-admin, so I had to delete my site several times now.

Regards,
Joyce

What is your *.000webhostapp.com url?
