Thank you. Just a couple more questions and hopefully this will be totally resolved:
So, can I remove the continue shopping button?
Do I leave the code after the closing html tag <?php @if(isset($_SESSION['eCart1_OrderID'])) unset($_SESSION['eCart1_OrderID']); ?> alone?
At the moment I styled the continue shopping button as style="visibility:hidden"
And this issue is resolved...
*!!!* I just retested, the order was processed; however, the checkout_success.php is not working; errors the first time and an internet explorer cannot open the page message on the second try. After all of this, the cart is not cleared.
I will remove continue shopping button and test again. Or do whatever you tell me I need to do.
Again: Retested again without the continue shopping button: http 500 Internal Server Error - The website cannot display the page. Then hit the back button, finally arriving at the empty checkout page. I clicked the view cart - it still contained items.
Okay, I am saving your changes in a folder and uploading the working version that won't clear cookies. Hopefully we can fix this soon.
