Hello! My domain is registered in Cloudflare, and I pointed it to Siteground hosting with an A record using the IP of my site (because Cloudflare doesn’t allow to change nameservers).
My website and the Wordpress admin panel work fine, but with I click on “Edit site” to modify things it doesn’t load and stays completely blank.
After a lot of back and forth with Siteground’s support, I’ve realized that when I disable the Cloudflare CDN cache by changing the A record to “DNS only”, the problem gets solved.
But then, when I change it back to “Proxied” the problem appears again.
How can I solve this? Sorry for the broken english
Are you maybe using the Flexible SSL setting in Cloudflare? If so, can you try to change that to Full (strict)?

What a genius! It worked!
It’s my first time on Cloudflare and I’m a beginner at this stuff. What is that change? It can affect the performance of my site?
Thank you Laudian
Hello @Laudian, I changed the SSL setting to Full (strict) as you suggested.
What other change should I apply now?
Thank you 
Full (strict) is essentially HTTPS.
Flexible means that Cloudflare uses HTTPS for the connection between Cloudflare and your visitor, but only HTTP for the connection between Cloudflare and your server.
This is (rightfully so) blocked by many applications, as it is insecure.
If you have any problems, it’s best you create your own topic and explain what problem you are facing.
