Woocommerce checkout stuck at "Thank you for your order. We are now redirecting"

  • Hi,

    I am using the PayTM plugin for woocommerce.
    On checkout, it get s stuck on:

    Thank you for your order. We are now redirecting you to paytm to make payment

    If I click “Pay via Paytm” before this auto redirection kicks in, I can successfully get to the payment gateway site, but I cannot use that workaround as the auto redirection kicks in in seconds and then the page is stuck there for ever.

    Here is the plugin code:

    <?php include(‘encdec_paytm.php’);?>
    <?php
