ActionView::TemplateError (comparison of Fixnum with nil failed) on line #38 of app/views/layouts/base.rhtml

The below error is another error related to upgrading Redmine. I imagine part of the reason I had a lot of errors is because I hadn’t upgraded this installation of Redmine, which we really just use for development, for a long time. In fact the upgrade took this installation of Redmine from 0.8.3 to Redmine 0.9.3. After I completed all of the steps in the Redmine upgrade I attempted to bring up the Redmine site in my Chrome browser but I received a 500 error from the LiteSpeed web server. The resolution was easy and is displayed below along with more details regarding the error.
