Hi there,

Theres a JS error being thrown on the checkout page –

It looks like the ‘conntections’ plugin is removing the version of jquery.validate that is shipped with WP and registering its own version.

If you temporarily disable that plugin and retest does it work?

As PayPal Express is currently in debug mode are you using a sandbox account login details within the payment method?

Thank you for your valuable reply.
I print the error while checkout to the payment gateway.

Here is the code where error occurred :
// Request Customer Details.
$request_response = wp_remote_post(
‘method’ => ‘POST’,
‘timeout’ => 45,
‘httpversion’ => ‘1.1’,
‘cookies’ => array(),
‘headers’ => array(),
‘body’ => http_build_query( $dtls )
// Log the response.
$this->log( array( $request_text . ‘ Response’ => $request_response), $payment );

Response of request response :

WP_Error Object
[errors] => Array
[http_request_failed] => Array
[0] => cURL error 35: error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure


[error_data] => Array

The sandbox for PayPal needs an SSL certificate on your site to work.

Do you have an active SSL on the site?

If not, then you can test by creating a new event with some low cost pricing options like $1 and then purchase them.

Afterwards, then you can refund the charge.

I made an error on my earlier reply. PayPal had made some changes including required TLS 1.2 or newer:

The connection is being rejected as it is an older technology.

Could you reach out to your web host about updating the server to meet those requirements?
