The theme is just here in Peru

in some places i can see the website but in anothers dont

shows up this error

~~http://i1140.photobucket.com/albums/n56 … -13-38.png">http://i1140.photobucket.com/albums/n564/zonageek/Captura%20de%20pantalla%20de%202016-01-28%2000-13-38.png" />

for example in my office I saw the website but in my home dont~~

If I visit the same URL as in your screenshot <http://cpl.org.pe/cgi-sys/defaultwebpage.cgi>, I get the same error page.

If I visit just <http://cpl.org.pe/>, then I get redirected to <http://www.cpl.org.pe/> which looks like a normal web site for "Cámara Peruana del Libro" (though I can't read Spanish).

Have you made sure to update your domain name server's at your domain registrar (godaddy, namecheap, etc)?

Your NS nameserver on domain registrar is OK. For the next steps, you have to set your DNS on Linode DNS Manager, there is tutorial to add dns zone here https://www.linode.com/docs/networking/dns/dns-manager

Did you add your domain to dns manager?
