I did a clean WP3.3 install
Everything goes well with the install
but after logging in the wp-admin i get a php error on:
foreach on wp-includes/class-wp-admin-bar.php on line 342
Also there are no widgets visible to drag and drop, not even the text widget.
I use the default twenty eleven + no plugins are installed, just a fresh install. I only get this problem on my live hosting. (PHP 5.2.6 + mysql 5)
