problems in "Archives" section

Hallo,

my website is: http://www.studioeticasoluzioni.it

when I go to the news page (www.studioeticasoluzioni.it/?cat=1), I’ve got an error clicking on the “archives” section (e.g. http://www.studioeticasoluzioni.it/?m=201507): the page does not show the news related to the month I click. Could you please help?

..And is there a way to translate “continue reading” in my language?

Thanks a lot!
