404 in preview, write post problems

Hmmm…I’ve now changed permalinks back to date/postname and preview is working again. This is on Apache 2.4…hmm…

OK, here’s what I think is happening. Somehow, WordPress is not updating the permalink when it previews the site. So if I return WP to the default permalink setup, the preview works. But if I change it to something else that should work (i.e. it’s syntactically correct), preview breaks.

While I’m the only one in here, I might also note that I used to have a thing for my sister.

I am having the same problem but I never met your sister.

OK. I have no solution, but I have more information about the same problem.

I can change settings to turn this problem on and off. But the off breaks a lot of other things.

I describe my set up and the problem in replies 8 and 9 here:

Summary:

With my setup described in the OP I have a working preview
In options setting the Blog URL to: “https://ministryofmanipulation.com/blog”
Custom permalinks name: “/%postname%/”
it looks for the preview at:
https://ministryofmanipulation.com/blog/?p=703&preview=true
and finds it ok
but that broke the admin “manage posts” link as described in other thread

Changing to the later setup described in reply=8 of that thread fixed that admin manage link.
But broke my preview! I cannot preview a blog post, or (pre)view an unpublished page.
In options setting the Blog URL to: “https://ministryofmanipulation.com”
Custom permalinks name: “/blog/%postname%/”
it looks for the preview at:
https://ministryofmanipulation.com/?p=703&preview=true
Does not find it and defaults to index

Suggestions?
Thanks
Drew
