opencart - Authorize.net confirm button "please wait" no redirection

Question

We are using opencart-1.5.6 and installed authorize.net(AIM) and PayPal as the payment gateway.But while we checkout using authorize.net, the card is processed and cash is deducted from credit card successfully, but the page is not redirecting to the confirmation page.Mail is sent successfully to admin and also purchase status is also set as completed.But the page still stuck in showing a please wait message. System is working in the sandbox mode and issue happens when its live. I would greatly appreciate if you can help.

As SankarV is recommending, exploring the response for the confirm AJAX request is the best bet - there might be no direct error in console, but since AJAX response contains invalid JSON due to possible PHP errors being printed out, the redirect to a success page could not be performed. So again, explore the AJAX response for the confirm request and come back with anything suspicious within it.

And though some entry_company might not take place in the checkout, since it is echoed somewhere while not instantiated, the PHP Notice is raised thus making the JSON response invalid...
