Oh well looking again, your script is incomplete. You need to send more data for a valid HTTP request, so I don't see how this could have been working before.
on *:sockopen:horoskopi: {
sockwrite -n horoskopi GET /horoskopi-ditor/shenja $+ %shenja1 $+ / HTTP/1.1
sockwrite -n horoskopi Host: $sock($sockname).addr
sockwrite -n horoskopi Connection: close
sockwrite -n horoskopi $crlf
}
