well, i could (i thin

) code an ACP thing for it, but not for today, and i don't know when i'm back next time
so, just the tip
open db_mysql.php
function query:
find
PHP Code:
$this->query_id = mysql_query($query_string,$this->link_id);
if (!$this->query_id) {
$this->halt("Invalid SQL: ".$query_string);
}
replace with:
PHP Code:
if(!strstr(strtoupper($query_string),"UPDATE") and !strstr(strtoupper($query_string), "INSERT")) { $this->query_id = mysql_query($query_string,$this->link_id);
if (!$this->query_id) {
$this->halt("Invalid SQL: ".$query_string);
}}
save the original as well

when you upload the hacekd file, no writing queries would be run anymore...
i don't know if it would work, because session also uses the updates but, just test it out
