Order total amount problems

[klk]

HELP!!

My website have the problems with the orders total amount.... the subtotal is ok, but the total amount is exactly 2.5 times the subtotal amount. i tried to disable the "orders total" at module, and only show sub total with shipping cost. But the problems remain when i install Paypal payment module which the total amount is 2.5 times again of my subtotal amount.

Another problem is in information box at left columm, it showed "box_information_privacy", i can't get rid of it, i already try columm_left.php but really have no idea whats go wrong.

if ((USE_CACHE == 'true') && empty($SID)) {
echo tep_cache_categories_box();
} else {
include(DIR_WS_BOXES . 'categories.php');
}

if ((USE_CACHE == 'true') && empty($SID)) {
echo tep_cache_manufacturers_box();
} else {
include(DIR_WS_BOXES . 'manufacturers.php');
}

require(DIR_WS_BOXES . 'whats_new.php');
require(DIR_WS_BOXES . 'search.php');
require(DIR_WS_BOXES . 'information.php');
?>

Any help will be appreciate.
