Redmine

Hello,

I'm new at redmine, I made my first installation using the latest version 2.3.2, ruby 1.9.3p194, and rails 3.2.13.
I'm on linux at bluehost.com. I've installed redmine following this tutorial: https://my.bluehost.com/cgi/help/redmine.

the problem is that whatever project is, the activity tab doesn't work. I always get Internal Error from the server.

I've got this log (but I can't understand):
