payment processing failed. please retry.

Hi there,
we are updating our site elearncollege from a test domain distanceacademy .But when I have updated stripe to the latest version 4.5.2 result in getting error ‘payment processing failed. please retry.’. on the woocommerce error log it shows an error object as follows
Error: stdClass Object
(
[token_id] =>
[customer] => cus_I9Gr19gDe348Aw
[source] =>
[source_object] =>
)
.there is no js error on console. I have created a new stripe account for test and added Test Publishable Key ,Test Secret Key ,Test Webhook Secret .Also added ‘add_filter( ‘wc_stripe_use_elements_checkout_form’, ‘__return_false’ ); ‘ on function.php and clean database using the foolowing query

DELETE FROM wp_usermeta
WHERE meta_key IN ( ‘_stripe_customer_id’, ‘_stripe_source_id’, ‘_stripe_card_id’ );
DELETE tokenmeta FROM wp_woocommerce_payment_tokenmeta tokenmeta
INNER JOIN wp_woocommerce_payment_tokens ON wp_woocommerce_payment_tokens.token_id = tokenmeta.payment_token_id
WHERE wp_woocommerce_payment_tokens.gateway_id = ‘stripe’;
DELETE FROM wp_woocommerce_payment_tokens WHERE gateway_id=’stripe’;

But there seems to be no way to sort it. I just stuck on it. will you have a look plaese?.
