I have a valid GeoTrust Rapid SSL certificate on my server for each one of the sites, and all showed the green lock in Chrome prior to setting up CloudFlare.
Yesterday I signed the sites up for CloudFlare (Pro) and within the CloudFlare settings chose Full SSL Strict for all six websites.
Three of my sites still show the reassuring green lock in Chrome:
The other three show the yellow triangle (This site uses a weak security configuration (SHA-1 signature) so your connection may not be private):
Would appreciate any help on getting these to work properly. Thanks!
