[Update: WordPress Support sent me an e-mail message saying that last night's problems didn't result from a hacking but from a "small server glitch." I'm leaving leave post this up, anyway, both because we have to take WP's word for that "server glitch" and because you might still want to change your password.]
Many people reported having trouble logging on to their WordPress.com blogs, which were apparently hacked, last night on Twitter. Some WP bloggers — of whom I was one — were redirected repeatedly to an unfamiliar site when they tried to log on. Others reported being hacked without saying why they thought their security had been compromised.
Some of the victims posted warnings on Twitter along the lines of: “Change Your Password NOW.” If you want to change your password, go to “My Account” (in the bar above the logo for your site), then go to “My Profile” or “Edit Profile.” At the bottom of your “Profile” page, you’ll see two blank spaces where you can type in your new password, then click “Update.”
One lesson of this slightly unnerving experience was that it helps to be on Twitter if you have trouble on a blog, because you can find out right away whether others are having similar problems: Search Twitter for “WordPress” (or “Blogger” or “Typepad”) and see if others are describing the same issues. WordPress also has a Twitter address, and you can try sending a message there. This brought quicker response than I’ve usually had by going to the WordPress Forums or sending an e-mail message to WordPress Support.
I believe I’ve solved the problem here and everything is fine — unless you were redirected to a suspicious site repeatedly when you tried to get to this one …
