This just started happening yesterday. Whenever I try and save draft / update a post, or click the preview button, I get a blank screen with the text “-1” in the upper left hand corner. Seems to be a variation of the WordPress white screen of death.
It’s only happening on posts, not pages. The posts still publish and update – the issue seems solely related to the admin add/edit post screen. I can still view the preview of a draft post by click on the permalink.
On a staging server, I tried disabling plugins, but that didn’t do anything. I switched to the default theme, and the issue went away, so it seems to be an enfold issue. Not sure if it’s php related or if it’s an nginx issue. Hosting company is Kinsta.
Nevermind. Think I fixed it.
It’s a conflict with the amp for wp plugin.
