Core WordPress files were modified

Are you using a plugin or service named “cloner”? Where was this file located? What are the contents of the file?

Happening to me too on several sites, though I’m using a different security plugin. No cloner plugin to speak of and the only contents are “Unhandled exception in file /path/to/cloner.php line 1762: [ws_closed]: Connection closed”. But there is no cloner.php at that path.

Wow, nope it’s from ManageWP: https://www.ads-software.com/support/topic/cloner-php-2/
