404 error in my pages

A 404 like this usually means that the folder of the website (probably pastoes.com/htdocs) is missing.

I don’t know what you mean by “translate the address to match pastoes.free.nf”. If you wish that the two websites should display the same content, you should add the domain as a parked domain/alias. Deleting the folder for another website is not the way to go and the server won’t magically bind the two domains together for you.
