 * The function `get_sites()` exists in WordPress core since WordPress 4.6.0 : [https://core.trac.wordpress.org/browser/tags/4.7/src/wp-includes/ms-blogs.php#L606](https://core.trac.wordpress.org/browser/tags/4.7/src/wp-includes/ms-blogs.php#L606)
 * Your issue could be related to how WordPress loads multisite core files during
   the install process of a plugin with the back-office install wizard.
 * We will run some tests, and if the issue is confirmed, we will publish a fix 
   soon.
 * For now, you should be able to use the plugin by installing it manually (download
   it, extract the archive, put the folder `multisite-clone-duplicator` into your`
   wp-content/plugins/` directory, and activate it in the admin.

 * I have already tried to install manually.
    I have done, ‘Deleted multisite-clone-
   duplicator folder and uploaded’, 2 times. Unfortunately the same error has occurred.

 * Ok,
 * We will run some tests and try to find why does it happen on some installations(
   because in most case, issue doesn’t happen).
 * We will release a fix as soon as we find the cause of the issue,
 * Bests regards,
