Upgrade 3.0 -> 3.2.1

[borgfabr]

Hello,

First of all, sorry for my english.

I'm really new on GetSimple. A teammate worked during one year about GetSimple and now I need to do it myself because he's gone.

I want to do the upgrade, for that i use WinSCP with root user but each time i want to upload a file following message comes :

General errror
Error code : 4
Message : failure
Asked code : 3

Please help me !

Another problem, i cannot change any page with root user in the cms, no right.... ????

Regards,

[borgfabr]

Problem is solved !
File system was read-only.
