Sorry, David, I seem to be breaking your stuff left right and centre.
I've been using Post Kinds plug to post replies to other websites, but then last night when I clicked on "reply" in Kinds, the usual URL bar (for pasting in the article URL I'm replying to) doesn't show up.
I thought it was because of one of the plugins I've installed, so I restored my WP back to an instance when the URL bar was showing. After the restore, Post Kinds starts working again, but after posting a couple of posts (without adding any new plugins) the URL bar stops showing again.
I'm not sure what I'm doing wrong.
In general, the problem seems to be that the Response Properties checkbox in the Screen Options (in the top right hand corner of the admin UI) doesn’t seem to remember its prior state. Thus I’ve needed to occasionally open the screen options and recheck the Response Properties box to see its meta box.
I’ve played around with it a bit, but can’t always reliably recreate the issue. It does seem to be happening less frequently now compared to when I originally upgraded. Is it possible that the checkbox state is only saved per kind?
