Good day and Thanks for trying out Super PWA plugin.
I just checked your website and seen that some images file’s on your website are not loading as secured (ie; not <strong>https://</strong>
). Even though SSL certificate is installed, the page doesn’t show a green padlock on browser, because not all links in the source are https.
As for progressive web apps, the website should be served fully via https://
You can either use a plugin like Better Search Replace: https://www.ads-software.com/plugins/better-search-replace/ to replace all https://
links with https://
(be careful and take a db backup before you do) or a plugin like this https://www.ads-software.com/plugins/really-simple-ssl/ to force SSL. Otherwise you can search the https://
links by checking the source code.
Here’s a quick report to know what all images are loading as non-secure. I think that will help you. If not, please do let me know.
