How to enable verbose logging (debugging) in ISPConfig 3?

In case of configuration changes do not get written to disk in ISPConfig 3, you should enable the debugging mode.

Login to ISPConfig and go to System > Server config > Server (name of the server) > Server

and set Logelevl to Debug.

Old Versions:

If you use an ISPConfig version < 3.0.2, then debugging has to be enabled in the configuration file:

Edit the ISPConfig configuration file:

nano /usr/local/ispconfig/server/lib/

and change the line:

$conf["log_priority"] = 2;


$conf["log_priority"] = 0;

The debugging information can be viewed in the system log in the ispconfig monitor and the output is also logged to the file /var/log/ispconfig/ispconfig.log

If you run a multiserver system, then you will have to enable debugging on the slave where the error occurs and not on the master node.
