SSL and Mixed Content

Hi Nobita,
I am changing my sites to SSL Certs.
conservativeaspects.com is my first.
In browsers I am getting “Mixed Content” with only one image that I can see.
The Word Press settings have been changed for HTTPS.

I have been searching for a fix and the most common one is to change the “http” to “https” (duh).

Here is what Chrome is showing me:
The page at ‘https://conservativeaspects.com/’ was loaded over HTTPS, but requested an insecure image ‘http://conservativeaspects.com/wp-content/uploads/2016/12/cropped-header1.png’. This content should also be served over HTTPS.

Suggestions are most welcome.
Jim
