good afternoon;
Further to a history(story) of right(law) roundcube posts(shows) me this
Installer script is still accessible The install script of your RoundCube installation is still stored in its default location! Please remove the whole installer folder from the RoundCube directory because these files may expose sensitive configuration data like server passwords and encryption keys to the public. Make sure you cannot access the installer script from your browser.
