Oh, I see. Everything worked fine up to version 7.2.1.
I use the WP File Manager to maintain my entire web server, not just my WordPress installation.
A function to access parent directories would be important for me. I don’t actually have anything to do within the WordPress installation.
Maybe you could add a switch that prohibits parent directories by default, but can be switched off after a warning message so that you have the complete root again?
