Error that the link with https, and you probably have, and https is not installed. So it redirects to the same exact but with http
and how to fix it ? I have installed the plugin SSL Insecure Content Fixer and I chose the option :
Grab all
The highest chance to break, but sometimes necessary

capture full page, correct the scripts, stylesheets and other resources
includes AJAX calls that may cause problems with compatibility, and performance
