hello i have transferd, a WordPress installation from one server to another and the quick-view is not working.
i did see that there is a this error in the console log:
Failed to load resource: the server responded with a status of 500 (Internal Server Error)
for this admin-ajax.php file.
i made another installation on my own computer, and it works fine.
same theme, same plugins and same WordPress version.
500 Internal Error is a generic error and says about some issue on the server and can be caused by different things. Anyway, to understand its nature you need to see your server error logs or enable PHP error display on the website. If you can’t do this, you need to contact your hosting provider for help in this question. Here is an article that may help you understand the error better http://www.wpbeginner.com/wp-tutorials/how-to-fix-the-internal-server-error-in-wordpress/
