admin-ajax.php returning code 0

We use this plugin on several sites with no issue. With the last few sites, we’ve run into issues creating new blocks. We see “0” whenever we click to “Create” button. Any ideas how we can track down the culprit?

EDIT: Resolved! The issue was being caused by the plugin’s jQuery dependency. The theme we are using recently released an upgrade that allowed us to determine if jQuery is loaded in the header or footer. We have found that if we load jQuery in the footer then we run into issues with CSS & JavaScript Toolbox on the admin side.
