Dont think either of them are AdvExt customers so that link will not help, it's linked to a private area.
Guess they should also post which version they are using because that will be different depending on which one. Code: function l2_additem2 ( $char_id, $warehouse, $item_type, $amount, $enchant, $eroded, $bless, $ident, $wished ) { // 55 - AddItem2, char_id, warehouse, item_type, amount, enchant, eroded, bless, ident, wished $cached_op = pack ( "cVVVVVVVVVV", 55, $char_id, $warehouse, $item_type, $amount, $enchant, $eroded, $bless, $ident, $wished, 1 ); $cached_op .= ansi2unicode ( $_SESSION [ "account" ] ); $ret_string = l2_cached_push ( pack ( "s", strlen ( $cached_op ) + 2 ) . $cached_op ); return ( $ret_string ); } But should have enough info to figure it out now.
