hi guys, just wondering if someone could give me a hand...

 

i keep getting a Fatal error: Cannot redeclare class ot_subtotal in /shop/includes/modules/order_total/ot_subtotal.php on line 13

 

i realise from other similar posts (not the same though) it is something that is trying to run/access it twice, but i'm not sure wat... if i rename the class ot_subtotal.php then i get an error on line 29 of order_total.php

 

now i can't find two lines the same as line 29, so i was wondering if someone could have a quick look and let me know.

 

much appreciated

fixed this, there are two repeated lines of code in payment_confirmation.php, i only thought one had to be removed, but it looks like both do

 

For anyone with this problem in the future, the file is catalog/checkout_confirmation.php. Comment out the second set of these lines.

 

require(DIR_WS_CLASSES . 'order_total.php');

$order_total_modules = new order_total;

 

That should fix things for you.
