Answered: Plz someone fix this error?

@pupi1985 Brother I want to know another thing because I do not understand this thing. What can I understand with this picture below? What sites will I do here? Set up my own domain?

E.g. https://eprosno.com

https://www.eprosno.com

eprosno.com

www.eprosno.com

Will I set up my own domain this way? Or another domain?
