In inspect and check the submit action in the network.

  2. requestSecureToken/ : return : return : {“payflowpro”:{“fields”:{“result”:“0”,“securetoken”:“XN0EtqbTdAkGjeijQjA4Ragdt”,“securetokenid”:“80e5ce6c085c57282b6a4a430e9b42e1”,“respmsg”:“Approved”,“result_code”:“0”}},“success”:true,“error”:false}

  3. payflowlink.paypal.com : return : response like html page :

How I fixed the issue:

  • Log into your PayPal Manager account.
  • Choose the ‘Service Settings’ option from the main navigation.
  • Next, choose ‘Customize’ from the sub-navigation.
  • Make sure ‘Layout C’ is selected and click ‘Save and Publish’.
