Same warning messages:
Stripe is enabled, but a SSL certificate is not detected. Your checkout may not be secure! Please ensure your server has a valid SSL certificate - Stripe will only work in test mode.
Your store does not appear to be using a secure connection. We highly recommend serving your entire website over an HTTPS connection to help keep customer data secure. Learn more here.
I checked with my hosting company, who also installed my SSL certificate; they said it is installed.
Thank you for your time; please advise.
