Owncloud 901 on raspberry pi directory unavailable


Hi. Messed up my Owncloud 901 on Raspberry Pi, so had to reload from scratch. User data is on external hard drive. All working, users are seen by oc but no files showing on web interface. Directory unavailable. I have changed the path in the config file. Not sure where to start .....


On the external hard drive I renamed the data folder to data.old, then I copied the data folder from the SD card to the hard drive. Now everything works, but I'll have to back everything up again.
