You can add anticapability for these commands using "owner defaultcapability", but that is only a temporary solution. There can also be other issues.
There are also two active Supybot forks, known as Limnoria and Gribble, which are actively developed and have fixed these issues. If you want permanent solution, you should install either of them.
I recommend Limnoria, because it seems to be more active (activity of Gribble isn't announced anywhere) and it has additional commands, translations and new plugin called PluginDownloader, which makes installing of 3rd party plugins easy.
-If you use Debian/Ubuntu or any Debian based distribution, you can get stable version of Limnoria here or testing version here.
