Over the last few days I’ve been getting people complaining that WordPress isn’t letting them comment because it says their e-mail address is associated with a WordPress account, and they need to sign in at WordPress, etc.
To be clear: I don’t know why that’s happening and it has nothing to do with how I’m running the site; on my end I have the same comment policy I’ve always had. This is possibly down to WordPress deciding to implement some internal dictum regarding people who have WordPress accounts, whether they remember that they do or not.
If you’re having this particular problem making a comment with your usual e-mail address, your options are signing into WordPress so it can authenticate you; using your Twitter or Facebook account to sign in and comment; or putting in a new e-mail address (real or not), not associated with WordPress, so it doesn’t bug you about it further.
I do apologize for this apparently arbitrary and silly thing that has nothing to do with me other than that I am hosted on WordPress, which I otherwise find a fine hosting option. I’ll look into it.
Update, 9pm: Matt Mullenweg of WordPress has an update in the comment thread.
