Redmine

Hi,

I speak french, but excuse me for my english.
I have a problem, I want to connect dropbox to redmine. Then for connect I use a plugin "Redmine Dropbox Plugin".

Look the plugin here: http://www.redmine.org/plugins/redmine_drop_box

I installed and configured the plugin on my Redmine and now when I want create a new project, I have a tab "DropBox", I can create new document, but I can't upload new file.

When I want to download a file, document or other I have this error: "Internal error An error occurred on the page you were trying to access. If you continue to experience problems please contact your redMine administrator for
assistance."
I watched in log file, but there isn't more information.

If someone know this plugin, can you explain exactly what this plugin. There is not much documentation on this plugin, so if you can help me on this point too nice. I think this plugin is just a sync with DropBox

Can you help me ?
Thank you for your help.
