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

3 common issues that users are facing.<\/p>\n

“-1” or “Failed To Verify Referrer”<\/strong>
\nThis means that most likely you are using a caching plugin like W3 Total Cache (W3TC) and the Javascript being minified\/combined and cached is outdated. Just empty the JS\/CSS cache under the “Minify” section of W3TC in WP-Admin and W3TC will regenerate it again. This will solve the problem.<\/p>\n

Password Protected \/wp-admin\/ Will Not Work<\/strong>
\nIf you are using .htpasswd to protect your \/wp-admin\/ folder, AJAX request to \/wp-admin\/admin-ajax.php will not work. This problem is not unique to my plugin. Any WordPress Plugins that uses the WordPress AJAX API<\/a> will break. As mentioned in this Codex, Hardening WordPress<\/a>:<\/p>\n

Simply securing the wp-admin\/ directory might also break some WordPress functionality, such as the AJAX handler at wp-admin\/admin-ajax.php<\/p><\/blockquote>\n

To bypass this, check out this tutorial, Password protecting the wp-admin directory<\/a>, this tutorial will teach you how to whitelist admin-ajax.php in your \/wp-admin\/ using .htaccess. <\/p>\n

I still hope in the future version of WordPress, they will separate front facing AJAX requests vs backend AJAX requests.<\/p>\n

Your WP-Admin Is HTTPS While Your Site Is Not<\/strong>
\nIf your WP-Admin is behind SSL aka HTTPS and you have the following config in your wp-config.php define('FORCE_SSL_ADMIN', true);<\/code>, the AJAX will fail because https:\/\/yoursite.com is different from http:\/\/yoursite.com and the browser treat it as different domain.<\/p>\n

To solve this issue do the following:
\nFind:
\n'ajax_url' => admin_url('admin-ajax.php'),<\/code>
\nReplace:
\n'ajax_url' => admin_url('admin-ajax.php', (is_ssl() ? 'https' : 'http')),<\/code><\/p>\n

What the code does is basically forcing http to be used when calling admin-ajax.php for AJAX request. Again this is a hack, I am trying to figure a way around it.<\/del><\/p>\n

I have pushed the code to trunk of all the respective plugins.<\/p>\n","protected":false},"excerpt":{"rendered":"
