Dear Guillermo,
Thanks for your support,
As you can see at http://www.elearningmaramici.it/moodle/ the upgrade is running also I had'nt change the name of directory,
I copied the journal and hotpot plugins into the Mod directory
You are authorized to continue the process and see what is exactly the problem
I think the problem is in the plugins.
Let me know what you think and what I must do
