Help! I updated, and now I can't access Virtualmin!

I updated to the most recent packages available a few days ago, and I haven’t been able to access my Webmin/Virtualmin Pro installation via the web ever since! What do I do?

My web sites are still available and functioning normally and I’m able to SSH into the box just fine.

Thanks in advance,
Andrew

Okay, I searched the forums and found some of Andrey’s troubleshooting advice.

There seem to be lots of SSL errors in my miniserv.error file, but the most recent errors are these:

Failed to bind to port 10000 : Address already in use
Could not listen on any ports at /usr/share/webmin/miniserv.pl line 456.
Failed to bind to port 10000 : Address already in use
Could not listen on any ports at /usr/share/webmin/miniserv.pl line 456.

Could that be my problem? If no, what do I do about it?

Thanks,
Andrew
