I fixed this problem by using the method suggested by kurtiskronk. I opened up the “header-default.php” file in the “Header” folder, and replaced the line wp-login.php?action=logout with wp-login.php?action=logout&_wpnonce=6baa6d3b28.
Now it works for me! Give it a try!
the simplest way I’ve found is to open the header_footer.jpg (found in the img file) in photoshop (or an equivalent) and edit to your heart’s content. I’ve managed to do this with Inove – you can see what I’ve done here: http://doayp.com/NCWD
