Use Joomla registration instead of Hikashop reg

Hi,

It's not possible to display the Joomla registration form inside of the HikaShop checkout if that's what you want.
The Joomla registration form isn't made to be included inside other forms. That's why we had to do our own registration form in the checkout.
Now if you're talking about the fact that you get redirected to the registration form page of HikaShop when you try to access the Joomla registration page, that's because you must have activated the Redirect Joomla registration to HikaShop plugin via the Joomla plugins manager. It's its purpose to do that.
