I need help about domain


I bought domain on Hostinger, after that I successfully parked domain, and linked it.
And I can now access to website with my own domain name.
But when I click on something, old domain 000webhostapp.com appears.
Does anyone know how to correct this error, or just have to wait, since I purchased the domain today?
thank you in advance
p.s. website name is www.kriptosan.online


Hi, this was a simple database issue and I have fixed it for you. Your site now loads fine with the new domain.


thank you friend, I have only one more question.
I find this tutorial on forum How To Use Cloudflare For SSL
Will it work for my website, because I see that my site now is not secure.
