Issue: XMLHttpRequest cannot load

My website page unable to display files and give empty popup on load. Below is the error from console:

XMLHttpRequest cannot load https://website.com/wp-content/plugins/wp-filebase/wpfb-ajax.php. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://www.website.com' is therefore not allowed access.

Please suggest.
