If you’ve just switched from test mode to live mode and Stripe seems to suddenly have stopped working you might not have an SSL certificate installed or you might not have your WordPress installation configure to use your SSL certificate.
LifterLMS Stripe will only function in live mode if your server has an SSL certificate installed and WordPress is configured to serve content using the SSL certificate.
For help purchasing or installing an SSL certificate, please contact your hosting provider or systems administrator.
For more information, please consult Stripe’s SSL Documentation.
We recommend WP Beginner’s tutorial on WordPress SSL for more information on WordPress and SSL certificates.
