[qmailadmin] Qmailadmin doesn't work!!

[Ely]

I have installed Qmail,vpopmail and qmailadmin with success a long time.. I got access for my users typing: http://myipaddress/cgi-bin/qmailadmin or hrrp://mydomainname/cgi-bin/qmailadmin. Well, I don't know what happened today I can't get access any more. I receive the following message>\ A p�gina n�o pode ser exibida . "the page doesn't can be showed "  translated for English. What do I have to do ?   Thanks   Elias
