Different pages shown depending on link clicked

-- HikaShop version -- : 2.3.5
-- Joomla version -- : 3.4.0

Hello,
I have an issue. Please check out:

hunterxci.under-development.info/hunter-xci-ply

In the right hand column is a Cart module and a custom HTML module that allows you to select options. Click the select options and add a product to the cart. You are automatically taken to the cart URL below, and clicking next displays the Login / register screen. This is all fine and works well.

hunterxci.under-development.info/component/hikashop/checkout

BUT ! If you browse to another page from here, and then click the Proceed to Cart button in the cart module on the right hand side it goes to a totally different URL:

hunterxci.under-development.info/component/users/?view=login

And does not go directly the cart page as displayed in the first URL above. How can I make the module go to the same page?

Hope that makes sense!

Thanks

Lee

Hello,
Can you make sure that the "Redirect Joomla registration to HikaShop Plugin" is published through your plugin manager ?
Thanks.

Thanks for the reply.
I have activated the plugin but it still does not appear to work correctly. I now get this page:

hunterxci.under-development.info/component/users/?view=login

And when I click Don't have an account to register nothing happens!

Hi,

Are you forcing a menu on the checkout page , in Configuration > Checkout > Checkout ?
If it is, please try another menu, else, try to force it.

Do you have edited the view "product / cart" ?
Do you have this line near the end of the view:
