Hi,
I am having exactly the same problems in that after upgrading from 0.2.7.4 to 0.3.x to 0.4.x, my MINI DLNA Plugin is non functional.
I un-intsalled the plugin before any updating.
The plugin file seems stuck on openmediavault-minidlna_1.0.23-cvs20111203-static-4_i386.deb
I have followed this post through but dont seem to be getting anywhere and may have made it worse.
Should I just re-install OMV?
Thanks,
James
