owncloud

Hello,

I tried to install the owncloud plugin because I want to use my server also as a cloud for myself and the schoolwork of my girlfriend.
First I tried BTsync but thats only for syncing and no storage on the server itself so thats why I want to use owncloud.
I downloaded the plugin and added the storage to the jail but when I want to acces the owncloud I get the fellowing message:
Data directory (/media) not writable by ownCloud
Dit kan hersteld worden door de webserver schrijfrechten...
