ConfigServer Community Forum

Only a certain reseller does not have access to the Configserver Firewall plugin.
As I did not find any problem that could cause this, I contacted cPanel support. And it looks like there's a bug. Here is the answer from cPanel support:

"At this time, all reseller privileges for ablhostc are configured correctly to allow access to the ConfigServer interface, however I do see that ConfigServer is still preventing the users access.

I manually checked the ConfigServer configuration files, and I see that ablhostc is listed correctly according to the ConfigServer rules:
=====
# grep ablhostc /etc/csf/csf.resellers
ablhostc::0:USE,UNBLOCK,GREP
=====

In this instance, there may be an issue with the ConfigServer software, which is preventing it from reading the line containing ablhostc. I would recommend reaching out to ConfigServer directly so they can assist you with further diagnosing their software."

If the reseller is seeing "You do not have access to ConfigServer Firewall." when going into csf then there is a problem reading /etc/csf/csf.resellers. The main reason for that is usually if the file has been edited and contains non-linux linefeeds.

The usual fix would be to use:
