uninstall iSCSI Target plugin

Hi guys

I'm relatively new to OMV, but did some investigation in the system, so I know a little...
Due to not thinking I installed iSCSI target plugin (but I need to USE an iSCSI target, not offer one).
But now I cannot get rid of the plugin. After uninstalling the dashboard service window bumps out error messages all 3secs (the #3003....)
I already read about it concerning other plugins, but all help offered for those did not work on the iSCSI plugin.
When reinstalling the plugin everything works in the GUI. But I would like to uninstall to keep the system clearly.

Any hints how to get rid of the plugin?

Thanks in advance!

thanks for the hint. Already did that.
Several reboots later uninstallation worked. Unfortunately I cannot reproduce what I did meanwhile. But nothing more than installing other plugins...
trying to mark thread as solved..
