Yes, I did. When I select address override with No address option, then I can move on to the checkout page; however, all fields are empty and the customer needs to re-enter all information. Address override + billing address or Address override + shipping address gives the following error: Unable to process payment. Please contact the merchant as the shipping address provided by the merchant is invalid, and the merchant has requested that your order must be shipped to that address.
If I select no address override and billing address or shipping address, then when I move on to the checkout page, I only can see country selected as Turkey (and PayPal language is correctly set to Turkish), first name, last name, phone number and email address. Shipping address box is empty. Also, maybe related to this problem: When I click Next button located on the shopping cart page, I get a warning about shipping before I can see the PayPal checkout page (attached). Warning in Turkish says something like "Shipping settings weren't set properly." I don't get this warning when the Joomla language is set to English instead of Turkish.
By the way, in my opinion, HikaShop is a great shopping cart application and I am hoping to resolve this problem, soon.
