Likely that. 1.0 marks a big change for sab vs 0.7 so I recommend deleting the config folder and starting fresh to be safe. Some of the settings changed. Remember to set the "article cache limit" to something like 64m or 128m as I found it likes to crash on Unraid with large downloads unless that value is increased.
There's definitely something weird going on with 1.0.0. I am not sure if it's an issue with the unRAID plugin or SABnzbd or both. In my case ever since I upgraded to 1.0.0 I get endless errors like this:
2016-03-27 11:47:25,100::ERROR::[config:842] Cannot create backup file for /boot/sabnzbd/sabnzbd.ini.bak
2016-03-27 11:47:25,100::INFO::[config:843] Traceback:

OSError: [Errno 1] Operation not permitted: '/boot/sabnzbd/sabnzbd.ini.bak'
Everything seems to work fine but the real problem is going in to the web interface and changing settings - this error seems to prevent any setting changes from being saved.
I also tried a complete clean start after nuking my config folder. I go to the wizard and set everything up but from there it seems unable to save the settings and sabnzbd can't be reached via the web interface. I think it gets stuck in a limbo where the ini settings cannot be saved and there aren't enough settings to launch either.
I've tried searching the net for similar issues and the closest thing I've come across is http://forums.sabnzbd.org/viewtopic.php?t=11051 where they are talking about the proper location of the config file. So could the issue be launching sabnzbd via plugin like this: /usr/local/sabnzbd/SABnzbd.py -d -s 0.0.0.0:5847 --config-file /boot/sabnzbd --pidfile /var/run/Sabnzbd/Sabnzbd.pid ? Maybe sabnzbd doesn't like where the config file is placed and gets confused?
