When I fill in the API user / password / signature with debug turned on I get this each time:
Fatal error: Cannot use object of type WP_Error as array in D:\InetPub\vhosts\mwccorp.com\caljts.com\wp-content\plugins\event-espresso-core-reg\payment_methods\Paypal_Express\forms\SettingsForm.php on line 202

Hi there,
That error means the request used to confirm your PayPal Express credentials are valid is failing and returning a WP_Error, EE is then trying to use a value from the response but its invalid.
This usually means there is an issue with the server preventing it from connecting to PayPal Express.
On that site can you install this plugin:
https://wordpress.org/plugins/log-http-requests/
Once that plugin has been activated go to Event Espresso -> Payment methods -> PayPal Express, provide your details and click save again (note it will again throw the error).
Now go to Dashboard -> Settings -> Log HTTP Requests.
Click on the ‘https://api-3t.sandbox.paypal.com/nvp’ request, does it show a WP_Error in the response field there there?

Sure thing, here’s the response:

{
"errors": {
"http_request_failed": [
"cURL error 35: error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure"

},
"error_data": []

Hi there,
This is usually fixed by updating your server OS so to the current stable version, which will usually include an update to OpenSSL. See also:

Can you contact your hosting provider to see if they can update the server?
