[avdanilov]

# vi /etc/sysconfig/selinux
# SELINUX=disabled
# reboot
# sestatus
SELinux status:                 disabled

Now it's OK

[vaemarr]

Seeing similar error (below). Any ideas on how to fix without disabling SELINUX?

At the moment the bot will direct message me but it won't post to group.

@Bazwalt
Two options:

1. Grant permission to the file
2. Learn how to live with SELinux if you don't want to disable it

[vaemarr]

Pretty sure I've granted it permission. I gave set +rw permissions.

What else could I be missing?
