Paymongo doesn’t work

Whenever I try paying thru credit card using Paymongo, the spinner just keeps on spinning and nothing’s happening. The order is created on Woocommerce but the status always says “Pending Payment”. Paypal payment option works fine, but we need to accept credit cards too.

Can you please fix this ASAP? I see that this is a similar issue happening with the previous topic.
