Jeez, I’m really sorry. For some reason the ownCloud add-on for the R4Sparc, R4x86 and R5ARM platforms was missing a file that in some cases prevented the admin panel from loading. I have no idea how this file got lost on the way into the add-on but I made sure it now is in there. So there’s a new version 0.9.3 of the ownCloud 6.0.1 add-on available for all affected ReadyNAS platforms. You should be able to grab the update from the “My Account” page. Again, sorry for the inconvenience.
