[Plugin: FancyBox for WordPress] Received this Notice:

Hi, I updated my wordpress and received the following notice after activating the plugin:

Notice: has_cap was called with an argument that is deprecated since version 2.0! Usage of user levels by plugins and themes is deprecated. Use roles and capabilities instead. in /home/flightsc/public_html/aviation-articles/wp-includes/functions.php on line 3466

Any idea on how I can fix this?
