I have been using the plugin for quite some time and I had not noticed this issue before. WP was recently updated but not sure 100% if that was the time the ratings stopped working. Since it only fails for non-auth users I did not notice until someone reported it to me.
Info
—————
WordPress version 4.7.3
Using DIVI theme
Multi Rating version 4.2.6
No WPML
No caching plug-ins
Recent Changes
—————
Recently updated to WP 4.7.3
Recently added AMP plug-in version 0.4.2
Hopefully you can narrow down the cause so our users can rate our posts again. Until then I am disabling the plug-in to avoid any confusion.
Thanks
I am having the same issue. Whenever any non-authenticated user tries to add a rating they get a 404 Not Found error calling the wp-admin/admin-ajax.php file.
Chrome console error:
POST http://docmgt.com/wp-admin/admin-ajax.php 404 (Not Found)
send @ jquery.js?ver=1.12.4:4
ajax @ jquery.js?ver=1.12.4:4
