After upgrading Bitnami Redmine from 2.1.4-0 to 2.2.0-0 many screens dont show up.

After following the defined process for upgrading from 2.1.4-0 to 2.2.0-0, and importing the old mysql database back. I am to log into redmine and it does show the projects. But I am not able to bring up any project issues or other screens.

I tried creating a new project, added one issue to it and clicked issues and got the same error:

Here is the error I see in redmine-2.2.0-0/apps/redmine/htdocs/log/production.log:

This blocks all progress - any help would be appreciated.
