---------------------------------

Já vi minha politica de segurança, o policy opis li foruns desse site.. mas deixei permissão para todos.

Já olhei a porta que uso, mas é a mesma. Também o host, conferi mas esta certo...

O QUE FAÇO AGORA ?
ALGUEM ME SUGIRA ALGO.. QUE NÃO SEI MAIS O QUE FAZER.

Grato
