New strange behavior

This has happened three days in a row now.

I write something using quick reply. Click "Post quick reply" , cloudflare askes me to verify I'm a human, I check the box, it thinks for a couple of seconds and then goes to a blank screen. When I restart VBF the post isn't there.

Luckily, I can use the post autosave and it restores the post. Then when I save the post it works fine. Never had this issue before.

I'm using Chrome.

Testing.....

EDIT:

CloudFlare checked me but I didn't get prompted to "Check the box." I'm not sure what the pattern is for when it shows the box or not.

My post went through as expected.

I'm using Chrome.

Cloudflare has asked me to check the box many time but it never effected my posts before.
