Redmine

I have upgrade my Redmine from 1.2.1 to 1.3.1 and I have problems with the old attached files (404)

I have maked a test downloading a new file and I look the name of the file in the directory files encripted, it's normal.

The old files names are not encripted... This may be the reason for the failure?

You can encrypt the names or disable the encryption?

Thanks in advance
