The use of the admin-ajax.php file by our plugin is necessary for certain features to work. This includes loading more posts with the “Load More” button, image resizing, and adding comments in the lightbox (pro version). Here are some common reasons this isn’t working:

1) There is a JavaScript error on the page

See our related FAQ for more info.

2) A security plugin or a custom rewrite rule in your .htaccess file is blocking access

Many security plugins have a setting to workaround this issue. The use of admin-ajax.php is the officially supported method for using AJAX with WordPress so many themes and plugins do this.

3) The WordPress Address or Site Address settings are not correct

These settings are found on the Settings -> General page in your dashboard. Make sure the protocol (http/https) matches what your site is using.
