I've switched my website from a single site to a multisite setup.
All is working fine except the cornerstone preview.
It shows this error:
The preview could not load due to a http/https mismatch. Please check that HTTPS is properly configured on your site.
Origin URL: https://www.roule.it
Preview URL: http://www.roule.it/
I'm working in https protocol.
Maybe the multisite is forcing the https protocol while in the latest preview I've worked in http.
What should I do?
Thanks in advance
