[PPPM-3732] Sites disappear from Wordpress Toolkit after WP 4.4 update

[ip00]

Today WP 4.4 was released. When I update a site it partially disappears from Wordpress Toolkit list. There is an item/line: "! /httpdocs" with a message "A Wordpress installation was previously detected at this path, but it is not operating properly now."

Plesk for Linux 12.5.30 Update #14
