Same issue with User root is not allowed to use the Nginx Webserver module

This is a freshly installed virtualmin, logging in as root user in virtualmin doesn’t let me access nginx webserver module.

User root is not allowed to use the Nginx Webserver module

How can I regain access to that module?

2

Obviously the answer on that thread is insane. Completely incoherent and nonsensical.

root should have all privileges by default. But, I guess something went wrong during installation.

Check Webmin ACLs for the root user in Webmin->Webmin Users->root and expand the Available Webmin Modules section. Check nginx and nginx ssl.

3

somehow Nginx Webserver is not checked while Nginx Webserver SSL is checked. Thank you!

4

That means the postinstall script didn’t run correctly when the webmin-virtualmin-nginx package was installed. Were there any errors or was it interrupted?

5

No, there are no errors and interruption. how to check and report the installation log to you?

6

There’s a virtualmin-install.log, probably in /root. That should show the apt/dpkg output, including errors.

I do not enable clamAV in virtualmin post install wizard

Hmm..Somehow that’s missing the actual package installation stage. Not sure what to make of that.
