I've created a test site for my client and I'm having issues with an ajax request on a product page. I have a error in the console: "Origin http://moore-web.com not found in Access-Control-Allow-Origin header", and the ajax request just freezes. It seems to be failing when the AJAX call is made to wp-admin/admin-ajax.php. I've added "header('Access-Control-Allow-Origin: *')" to the file, and the error seems to stop displaying in the console, but it still doesn't let me checkout. I also attempted to add "callback=?" and ensured the the "Wordpress Address" and "Site Address" are the same with no luck. This seems strange because it's making the request on the same domain. Chrome, Safari, and Firefox all seem to work fine.
