Been trying to resolve this one for a while. I have the Thrive Ovation testimonial manager, it works fine unless a subdomain site has a mapped domain. Then I get mixed content errors..
I have forced HTTPS in Admin on (WPCONFIG)
I have also Force Original HTTPS in Admin (DOMAIN MAP CONFIG)
I have also tried two plugins to FORCE HTTPS to fix mix content script errors.
None have helped so far.
-SSL Insecure Content Fixer
And I still get this continued error in the browser console.
load-scripts.php:4 Mixed Content: The page at 'https://shadowtarot.lightworkers.org/wp-admin/admin.php?page=tvo_admin_dashboard#testimonials' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint 'http://shambhalawisdom.com/wp-json/tvo/v1/testimonials?_=1493260436464'. This request has been blocked; the content must be served over HTTPS.
Any suggestions.. Thrive just tell me to speak to my Hosting Company.. We run a VPS server.
