Some of the most popular or more commonly used WordPress plugins in the community are plugins created by Lester Chan. About a two weeks ago, he released an update for the WP-Email, WP-Polls, WP-PostRatings and WP-PostViews plugins that included some changes like assigning the /wp-admin/admin-ajax.php file to handle AJAX requests.
Due to those changes some users are experiencing AJAX-related problems. Below are the two most common issues:
- “-1″ or “Failed To Verify Referrer”
- Password Protected /wp-admin/ Will Not Work
If you are using of the plugins mentioned earlier and are experiencing any AJAX-related issues like the ones listed above, please check out Lester Chan’s most recent blog post for further details regarding the issues and how to fix them.
