Hi,
It happens, because the ajax handler is not accessible on your server, possibly because of an incorrect .htaccess rule.
You can test it by visiting this URL on your site yoursite.com/wp-admin/admin-ajax.php
If it works correctly, it should return a simple white page with a 0, like so: https://i.imgur.com/JCAAIvE.png
Also, make sure this option is turned off, once you fixed that issue: https://i.imgur.com/zhEUUew.png

Same issue but the error is:
The request failed. Please check your connection! Status: 500
I tested it by going to yoursite.com/wp-admin/admin-ajax.php and it shows me 0
So i remembered i recently changed my site to PHP 7.1 instead of 7.0 that i was using before, and voilá, i fixed the problem by reverting to PHP 7.0.
One last question, if i mark “Use custom ajax handler” as ON the explanation is “Usually it has great performance impact.” Does that mean that if turned ON will have better or worse performance?
Thanks!
