I have set up a nopCommerce site. I'm using Ubuntu 18.04 LTS and nginx. I used Let's Encrypt to obtain an SSL certificate for my site.
When I go to my website it's "secure" for everything except the pictures. I don't have any custom plugins, only the Nivo Slider. I've seen comments elsewhere how the image itself could be pointed to a NON-https url. That's the case here, but I have no clue how to correct that.
If i go to Admin > Configuration > Store and enable SSL my Admin panel is not reachable. I have to correct the record manually in the DB to turn SLL off.
I've seen other topics how this is likely an issue with my certificate.
Here is the report for my certificate: https://www.ssllabs.com/ssltest/analyze.html?d=preview.jnsfullstack.com As far as I can tell everything looks fine.
I used the Certbot CLI to install my certificate: https://certbot.eff.org/lets-encrypt/ubuntubionic-nginx
I turned auto-redirect to OFF and ON, both cause the same issue.

On pages with no images the website is fully secured.
