Rublon Account Protection for WordPress

I use this simple, very nice plug-in from Ciaran Gultnieks to hide the black bar at the top of the new WordPress 3.8 front-end, and to hide/show the WordPress toolbar:
After attempting an automatic update to my self-hosted WordPress install from version 3.6.1 to version 3.7, within the admin panel, the site returned a completely blank page… I was unable to log back in to the admin panel at all, and the public site was down as well. The resulting URL displayed in the window contained:
../wp-admin/upgrade.php?_wp_http_referer=%2Fwp-admin%2F
…and in the the error log (viewable via FTP) was the entry:
Call to undefined function wp_get_current_user() in /wp-includes/user.php on line 215
In the WordPress.org › Support » Installation forum, user photoMaldives had the fix posted here… nice job.
I’ve been incorporating two-factor authentication wherever I can in my digital life, and mobile apps like Google Authenticator can make it a snap to implement, especially with easy QR code verification. But until now I hadn’t found a solution I liked for WordPress, having tried a number of different plug-ins, only to later uninstall. Enter Rublon, a mobile authentication app I saw reviewed (along with several other apps) on the Torque website, by contributor Jay Hoffmann. The Rublon app and its WordPress plug-in work perfectly for my purposes, easy to implement and very similar feel to the Google Authenticator process. It’s an additional security layer on top of your existing log in authentication, and with the Trusted Devices feature, you only need to set it up once in any given Web browser, and you can forget it… highly recommend.
Nice update today for Jetpack by WordPress.com, version 2.4…
Changelog
2.4
Facebook posts with privacy set to “Public” can now also be embedded in Web pages and blog posts by anyone. An “Embed Post” option is in the arrow drop-down menu at upper right corner, viewable when logged in to Facebook. Here’s an example of an embedded post from my Facebook musician page:
Here are a few WordPress plugins I have been really happy with lately:
Admin Bar Minimiser
Minimizes (and brings back) the WordPress admin bar at the click of a button, very nice…
Awesome Flickr Gallery
Creates a photo gallery of your Flickr photos with many customization options, uses the Flickr API… powers the sidebar widget here.
Dynamic To Top
Very nice with lots of options, JQuery-powered… at lower right on these pages.
Plugin Organizer
Selectively disable plugins on any post! (And many other powerful features.)
