checkout_pane and checkout progress pages

Hello,

I am very new to drupal and I am have problem with the commerce checkout_pane and checkout progress pages.
The checkout page are:

Checkout (Machine name: checkout)
Shipping (Machine name: billing)
Confirm Payment (Machine name: shipping)
Payment (Machine name: review)
Payment (Machine name: payment)
Checkout complete (Machine name: complete)

checkout form (checkout pane)
Checkout:
Shopping cart contents
Coupons
Shipping information
Billing information
Shipping
Shipping service
Confirm Payment
No panes on this page.
Review
Review
Payment
Payment
Off-site payment redirect
Complete
Completion message

I have a block page for the checkout progress that allows the progress direction i.e “cart > checkout > shipping > payment > checkout complete.” on each stop of the checkout process.

I am getting a 500 error after the payment page on the redirect. I am to process the credit cards getting a valid credit card authorization code. when I check the order status it shows that the status changes from review > payment to complete, everything works but the page does not redirect get the 500 error and when I refresh the page it goes to the complete page.

Is there a was for me to redirect to the complete page after I submit the credit card payment.
