# Cannot determine payment method.

 * I have entered Production Merchant ID, Production Private Key and Production 
   Public Key. The test connection was successful. I have also enabled Braintree
   Payments and selected the same payment methods as configured on braintreepayments.
   But still I am not able to place an order. In the debug log it says:
 * Message: Cannot determine payment method. Error Code: 91508
 * What I am missing?

 * Hello [@theycallmegosu1982](https://wordpress.org/support/users/theycallmegosu1982/),
 * Please reach out to us at [support@paymentplugins.com](https://wordpress.org/support/topic/cannot-determine-payment-method/support@paymentplugins.com?output_format=md).
   This issue can arise when you have jquery or javascript errors on your checkout
   page which interfere with the WooCommerce ajax call. In your email to support,
   include your website.
 * If anything interferes with the ajax call made by WooCommerce, the form will 
   be posted to your server which circumvents the submission of all necessary data,
   including the payment method nonce, which Braintree uses to process the transaction.
 * Thanks,

 * Update on issue:
 * The OP was using version 2.3.8 of WooCommerce. It is highly recommended to stay
   up to date with the latest version of WooCommerce.
