Lester ‘GaMerZ’ Chan has published a post on his personal site that addresses two common issues users are facing right now as they relate to AJaX.

About 2 weeks ago, I release an update to r WP-Email, WP-Polls, WP-PostRatings and WP-PostViews which added some nonce check and moved the AJAX request to be handled by /wp-admin/admin-ajax.php.

Lester explains what each issue is along with the solution.
