#45742 new defect (bug)

When using HTTPS, "preview post" fails.

I am using WordPress 5.0.2 hosted at HostGator, but have been seeing this issue since 5.0 was released. I am using the Classic Editor plugin.

If I log into my WordPress site using https://(site), write a post, and then click "preview", WordPress will wait and then say the post cannot be displayed.

If I log into my WordPress site using http://(site), write a post, and then click "preview," WordPress with show a preview of the draft as expected.

I have tried disabling all plug-ins and it did not fix the problem. HostGator forces WordPress users to use "Endurance Page Cache" plug-in, so I cannot disable that one.

I have multiple WordPress sites hosted on HostGator (,, and all of them have been having this issue since upgrading to 5.0.

Hopefully I found a legitimate bug and didn't waste anyone's time. Keep on 'Pressin!

Hello @robohara , welcome to WordPress Trac!

To help pinpoint the particular issue, can you use your browser to developer tools, repeat the same steps, and provide us with a list of requests it makes, and their statuses? A screenshot will do as well.

Open your developer console (F12 in Firefox), and go to the "Network" tab. You will see a button to clear the list, and it will automatically record all new requests to the server when you make changes in the Editor.
