Wordpress admin-ajax results in Error 302 redirect

Question

I have customized a plugin to make some ajax calls to admin-ajax.php and it works great. I copied the code over to another site and it no longer works for users who are not logg

Answer 1

I had something similar occur in a theme. The original coder was trying to prevent a non-admin user from being able to see the /wp-admin/ area.

Here's an example:

// Block Access to /wp-admin for non admins.
function custom_blockusers_init() {
  if ( is_user_logged_in() && is_admin() && !current_user_can( 'administrator' ) ) {
    wp_redirect( home_url() );
    exit;
  }
}
add_action( 'init', 'custom_blockusers_init' ); // Hook into 'init'

I would check your theme for source code similar to what I have.

When you find the code, just add an extra conditional to make sure that a user isn't redirected if the DOING_AJAX constant is defined.
