Still a Mixed Content issue. Using Dev Tools in Chrome, I see several images with http in the URL.
It’s possible you have HTTP hard-coded in some of your content. But for starters, I’d make sure WordPress Settings-> General has your Site URL set to HTTPS.
Then at Cloudflare’s Crypto tab, turn on Always Use HTTPS (you probably already did this) and Automatic HTTPS Rewrites (at the bottom of the Crypto page).
If you have wp-cli installed on your server, you can also do a search and replace for http://example.com:
wp search-replace ‘http://techsable.com’ 'https://techsable.com’
Some WordPress plugins can do this as well.
