Redmine

I got this error when I tried to edit an item on Wiki. I use utf8 at my database and at the system.

Before I was using Ruby 1.9.2 and a thread at this forum show me to use the 1.8.7, after I made a downgrade, this error doenst appear anymore, but I got Internal server Error.

My Redmine Version is 1.1.2

I looked at my production.log and got this:
