I'm not certain which set of options I've selected that have hidden the C.O.D. payment option. Looking at the source, the code for COD is there but it doesn't display in the browser. I believe it's being hidden by this javascript at the end of the checkout_2_method.tpl file:
Code:
<script type="text/javascript">
<!--
var paymentsCOD = [{strip}
{foreach from=$payment_methods item=payment}
{if $payment.is_cod eq "Y"}
{$payment.paymentid},
{/if}
{/foreach}
0
{/strip}];
display_cod({if $display_cod eq 'Y'}true{else}false{/if});
-->
</script>
C.O.D. is selected in the payment options page in the admin section, but I have no idea why it's being hidden. What setting am I missing?
