Hi, I have the same issue, I've accidentally enabled network management in ISPConfig and now all services are unavailable. How do I disable it? Could'm find any related settings in both config.ini.php files. Latest ISPConfig 3
You should not revive 10 year old threads. Post a new question, there you can link to this ancient discussion if needed.
I moved it to a new thread. To your problem, there is no need to disable it in ISPConfig. Fix the /etc/network/interfaces file on the shell. Afterward login to ISPConfig and disable the checkbox.
