Hi Tom, same problem with me. (ReadyNas OS 6.12, Bt Sync version 1.1.70) I adressed this problem to the Readynas Forum and rxnextras.com, nothing happend 'til now. I think it has to do something with the owner right of the admin account. It's working on the Synology NAS. Though the share can not be created, the Webfrontend won't start up, I think. You can acces the rnxtras Website via: http://rnxtras.com/addons/bittorrent-sync-readynas-6-all I hope that they will fix this problem soon. We'll have to wait :-( Keep me posted if something happens...retox "Hi guys, I tried to install the Bittorrent Sync App 1.1.70 implemented by Poussin. (Readynas RN-102, everything up-to-date) Everything worked fine, but when I fired up the app, there was an error in the log when starting the app via the ReadyNas webfrontend saying that the btsync folder creation failed (‘btsync’ creation failed). The second thing is, that when I login in into the btsync server webfrontend, nothing happens (I think this is because of the missing btsync folder). I rooted into the NAS and tried to check the btsync config and the startup init, though I’m not a great “script translator” I decided to write this post. Am I missing something? Do I have to turn on a certain services? Please show me the magic... Anyway, thanxalot to Poussin for adding this nice app to the repository retox"
