One of our sites Supercars For Sale was displaying an error message:
Warning: Invalid argument supplied for foreach() in “..”/class-wp-admin-bar.php on line 342
This occurred after the 3.3 upgrade.
The problem is caused by the theme – in this case “elements of seo” having TWO calls to wp_footer (one direct call, and a do_action).
The solution was to remove the do_action call.
That’s it. Sorted.
