  • Can you say what CSF is blocking on your server?

    csf is blocking ? what do you mean ?

    I’ve made the assumption that CSF is ConfigServer Security and Firewall (CSF)

    Blocking things is what firewalls do, so we need to know what it’s blocked in this instance.

    okay :

    He block this ip :

    I’ve this in lfd :

    May  6 21:10:25 vps62122 lfd[1786]: *Suspicious Process* PID:1238 PPID:21486 User:******* Uptime:117 secs EXE:/usr/bin/php CMD:/usr/bin/php /home/******/public_html/wp-admin/update-core.php

    But not blocked, yhis is my config :

    ST_ENABLE		1

    Well it seems clear that CSF is stopping the updates for some reason. I’m unfamiliar with configuring that tool, I use iptables directly.

    Maybe ask in the CSF forums (via the link I provided above).
