ERR_NAME_NOT_RESOLVED

Un site in care nu pot intra si nici emailurile nu mai sunt fuctioanle chiar daca au fost instalate corect in 2013.Ma puteti ajuta cu eventuale solutii sau care au fost cauzele. In acest moment, chiar daca in public_html gasesc folderul aferent domeniului, siteul nu e functional si nici accesibil, am dezactivat pugginurile deja, in plus nici adresele de email nu sunt functionale
Eroarea este urmatoarea The server at partronatulpsihologilorbucuresti.ro can’t be found, because the DNS lookup failed. DNS is the network service that translates a website’s name to its Internet address. This error is most often caused by having no connection to the Internet or a misconfigured network. It can also be caused by an unresponsive DNS server or a firewall preventing Google Chrome from accessing the network.
