I just installed and “Enforced” letsencrypt on a new single page https://taxiaguachica.com hosted by siteground. Upon visiting I see:
Firefox says "Parts of this page are not secure such as images"
Google Chrome says "Your connection to this site is not fully secure"
It is created with WP/divi, has one photo, some html that converts two phone numbers (text) to links to visitor’s cellular dialer, and a plugin that displays a phone icon and also creates a dialer
There is no function on the site which requests or receives information
Hosted by Siteground
My operating system test visited with windows 8.1 and Sierra 10.12.6
My web server is (include version): Host? Linux is this what you’re asking?
My hosting provider: siteground
I’m using Cpanel/ wordpress
Is there something I need to do with photos? or is it a plugin?
