One of my sites was getting this error when using WP Clone by WP Academy
I saw posts saying WP Academy wasn’t compatible with the newest versions of WordPress and recommending people to use All-in-One WP Migration or XCloner.
While both are good backup programs, I found an easy fix to get rid of the error.
I just upgraded the PHP version in my site’s cpanel from 5.4 to 5.6 and that eliminated the error. WP Clone works perfect now.
Hope this helps!
