Last week I created a new post as a followup to the previous one some months ago, after first upgrading to 2.9.2.
But when I published, everything on the blog except the title and the post title disappeared.
I trashed it, everything came back, untrashed it, everything went away again, so I trashed it again, created a new post with the same content.
Same result.
Left it a while, came back to it today (with a different browser even) thinking the theme might be causing the problem, and tested some other themes, after untrashing the post again.
No difference, the blog had practically disappeared.
On the off chance that it had something to do with the content (unlikely I would have thought), I am writing this post as a test.
Lets see what happens…
