Problems when uploading a csv file

[aleix.zam...@gmail.com]

Greetings,

My name is Aleix and i recently installed a ckan on my virtual machine (Ubuntu 14.04 LTS) and i'm having problems when i try to upload a csv file, because i have the field to upload it but once the dataset is uploaded it gives me a 404 error, it's like the csv file hadn't uploaded. Does someone know how to fix it?

PS: I attatched two screenshots to explain the problem clearly.

Thank you,

Aleix Zamorano
