Unexpected unfinished ckeckout process

-- url of the page with the problem -- : www.ma-collective.com/component/hikashop/checkout?Itemid=252 (after login)
-- HikaShop version -- : 2.6.0
-- Joomla version -- : 3.4.6
-- PHP version -- : 5.3.29
-- Browser(s) name and version -- : Firefox 44.0.2
-- Error-message(debug-mod must be tuned on) -- : None

Something goes wrong during the checkout process.
SCENARIO 1
1. I select a product from the list (as a Guest) and click on Add to cart button.
2. I click on Proceed to checkout.
3. I need to login (which is ok).
4. In the checkout screen I click on Next ( I deliberately do not tick the T&C box (although this doesn't make a difference).
5. This is the url (IMPORTANT): www.ma-collective.com/component/hikashop...ep/step-1?Itemid=252 .
6. So, when I click on Next, I come on the Home page without any notification.

SCENARIO 2
If I then go to the Cart, the prduct is there. I click on Proceed to checkout. And here it comes: the url (IMPORTANT) is different: www.ma-collective.com/component/hikashop/checkout?Itemid=252
And than everything works fine.

So my question is: what goes wrong in scenario 1?

Hi Nocolas, Thanks for your quick respons. I enabled/activated your account. Kind regards, Hans

Hi,

I tested it with IE and Firefox, both times with your account. Maybe to make more clear my problem:

If I.m not logged in, I put somethoing in my cart. I choose to Go to Payment. Then I need to login. After that I choose to proceed. Two things happen: there's no check on my T&C and I end up on my Home page without anything happening. Then if I go to my Cart, the checkout process is fine...

Hi there,

I'm starting to believe this might have something to do with language. I asked another Dutch user to do the test and his findings were the same as mine unfortunately. We used to have a second language (Dutch) in Hikashop, but before the launch we changed this back to English only. Is there a way for you to check? Would you mind having a look at te configuration in the backend? You could change your password and after that I can promote you to Super user...

Kind regards, Hans

But the main thing is: after login ...
I get on this URL: www.ma-collective.com/component/hikashop...ep/step-1?Itemid=252
and you: www.ma-collective.com/component/hikashop/checkout?Itemid=252
What could possibly cause that?
What happens if you use my URL and click on Next?

Hi, this is tough. I understand that it's hard to find a solution for an issue that isn't reproducable for you. By the way, to be clear, this isn't a multilanguage site anymore, so you can't switch languages. But the only difference I could think of, is that you probably use an English browser, while I use Dutch. So it was only an assumption that this problem might has to to someting with language. But I did another check on language settings throughout the site and couldn't find anything suspicious.

So, I was wondering, is it possible for you to take over my PC remotely, like with TeamViewer software?

One thing I discovered during my analysis (maybe it can help you):
After login, I get on this page: www.ma-collective.com/checkout/checkout/task-step/step-1 , I copy the url
After Next, I get on the Home page
I past the url www.ma-collective.com/checkout/checkout/task-step/step-1 and now it works fine!

Hi Nicolas, good news! Your suggestions put me in the right direction. I finally discovered a component which redirects users after login. I disabled it and everything works fine now. Funny thing though, this apparantly didn't apply for your test account. But anayway, I'm happy and very grateful for your help!

Kind regards, Hans
