Issues with checkout

Newbie with Hikashop please bear with me

Noticed a few issues with my checkout process and would appreciate any help:

1. Cart is not cleared after order is complete
2. I have to press the 'Next' button twice on the Address and Payment steps, not sure why this is happening? My flow is currently set as follows: login,address_shipping,payment_confirm_coupon_cart_status_fields,end.
3. How can I bypass the 'Login' step of the flow if user is already logged in? Currently it takes the user to the login step but there is no content displayed.

Test User-
Login: pcb_test // password

My Hikashop version: 1.4.8

hmm that's bizarre, I just tried again myself and couldn't reproduce it either...some kinda phantom bug?

Cool, I appreciate the quick response and your help Nicolas. I'll let you know if I see it again, so weird..

If you're still here, do you know why I'm getting this error when I logout? I think it's a Joomla problem, not Hikashop, but thought I'd just run it by you

Fatal error: Class 'hikashop' not found in /home/kennethpho/www/www/Joomla/plugins/user/hikashop.php on line 80

I checked my hikashop.php as per the thread u linked, and mine already has the fix. Is there something else I'm missing?

ok i see discrepencies now, what function is this supposed to be in? Is it supposed to be in here:

function onAfterDeleteUser($user, $success, $msg){
if($success===false) return false;
if(!include_once(rtrim(JPATH_ADMINISTRATOR,DS).DS.'components'.DS.'com_hikashop'.DS.'helpers'.DS.'helper.php')) return true;
$userClass = hikashop::get('class.user');
$user_id = $userClass->getID($user,'email');

Because i noticed the $user_id line, is different on the right side than what you posted on that thread. Should I replace that too? or is this the wrong line? I can't find the following second line specified in the thread you linked:

$user_id = $userClass->getID($user,'cms');

UPDATE:
I don't think I changed anything, but now it looks like it's working as well suddenly...strange. I'm seeing things today, lol. Thanks again for your help Nicolas
