Earlier today I was updating the website to a new theme. And I clicked a button that said import, then after I clicked it, I realized in horror what it was going to do.
It imported all the posts from the theme’s test site and made them into new posts on this site, all 50-something of them. Ugh.
Worse still, it emailed each post to everyone who is subscribed to receive new posts by email, so sorry about that, I was annoyed by it too.
I think everything is under control now so that shouldn’t happen again.
