404 when making request to admin-ajax.php

[itzrahulsoni]

I am using the latest version of the plugin and I can see the following line in the application.php as well. But still, I am unable to call admin-ajax.php file. Looking at the repository history, this seems to be fixed... but my deployment says otherwise. I am able to get it to work if I am logged on. If I disable this plugin, I can see that the page works. Please suggest.

$no_check_files = array('async-upload.php', 'admin-ajax.php', 'wp-app.php');
