Recently Cloudflare turned on SSL for sites, the problem

Recently Cloudflare turned on SSL for sites, the problem I’m having is that all my WordPress sites are breaking under https:// vs http://

For example:

http://killingtoncabin.com/ – loads fine

https://killingtoncabin.com – looks like it’s failing to load something

Same with discoverbuenosaires.com, snowdaze.com, etc.

This happens across all my WP sites. Any idea what the problem is?
