    I followed these instructions exactly. Now I cannot access my server via Plesk Administrator, nor via SSH, plus all of my sites refuse to connect. In other words, this has completely destroyed everything...!

    I would recommend you submit a support ticket so we could check the issue in more details:

    I suppose that you have encountered a similar error, since these bugs appear only on Debian/Ubuntu. Try to search for other articles that are applicable for CentOS 7 using the exact error messages.

    I think my error looks really similar

    "Der ModSecurity-Regelsatz konnte nicht installiert werden: modsecurity_ctl failed: gpg: key 4520AFA9: "Atomicorp (Atomicorp Official Signing Key) <>" not changed gpg: Total number processed: 1 gpg: unchanged: 1 gpg: Signature made Tue Jul 2 01:09:11 2019 UTC using RSA key ID 4520AFA9 gpg: Good signature from "Atomicorp (Atomicorp Official Signing Key) <>" gpg: WARNING: This key is not certified with a trusted signature! gpg: There is no indication that the signature belongs to the owner.

    Hello @Roman Gräbner,
    This error is too generic, could you please share details?
    Is this the full message?
    Are you able to log in using login/password from /etc/asl/config file?
    What is the output of the following command:
    plesk -v
