Hey guys.
I just can’t insert posts in WordPress with Cloudflare proxy enabled.
If I change it to only DNS it works fine.
It was working fine until today, but I discovered that its not doing fine with the proxy on.
Can anyone help me? Please.
May I ask you to share some feedback information, like if you get some error presented or? 
Can you share a screenshot of it, if so?
Is it the error in the “Console” tab of the "Web Developer Tools (press F12)?
Before moving to Cloudflare, was your Website working over HTTPS connection?
Are you using “default” editor like Gutenberg or “classic” one, or some other 3rd-party plugin for Visual Builder, etc.?
May I ask what SSL option have you got selected under the SSL/TLS tab at Cloudflare dashboard for your domain ( Flexible, Full, Full Strict … )?
May I ask have you tried using a different Web browser, or tried clearing your Web browser cache?
How about using a Private window (Incognito mode) or a VPN connection if possible?
Is it the same behaviour on your mobile phone (4G LTE, mobile data, cellular)?
Hey there.
After trying to publish or edit a post in the website, this new page just doesn’t load.
It stays in a blank page
At the Depeloper Tools there is an error: Failed to load resource: net::ERR_QUIC_PROTOCOL_ERROR
I always used Cloudflare at this site. I was working fine before.
The website was built using Elementor. For the post types I’m using the Gutenberg as editor.
The problem is not with Elementor because I can edit the pages (like Home) normaly with Elementor.
The SSL option selected is Flexible.
While with the proxy option selected, I tryed to add a new post with Chrome and Opera (normal and incognito mode). It doesn’t work in any option.
While with the only DNS option selected, it worked fine in Chrome and Opera normal mode.
Clean the cache doesn’t chage anything.
Didn’t try using VPN or in mobile phone because I’m trying to edit the posts.
The pages load normally in any device, but I cand edit them.
I can confirm this is happening. We have 3 dozen plus domains on Cloudflare/SiteGround most of which with Elementor/Elementor Pro. Some use other builders or templates like Flatsome and Avada. The Elementor sites all experience the issue outlined in the post and if we disable the Cloudflare proxy the problem is resolved.
