Shoot..! One of the best, most used plugins is now broken on WP 3.5.1.
Installing is ok, but when I activate it and click on "Update" the website logs me out, and I can't login back (unless I go "back" on my browser).
I really need this asap so unfortunately I' forced to use another plugin, which I'm researching at the moment.
Will be delighted to go back to this once it works.
