Redmine

Hi all,

I am trying to upgrade from Redmine 2.3.3 to 3.0.3.

Everything appears to go to plan until I start the webserver and attempt to touch the homepage. I get a 500 internal error with an error message in the production.log.

My environment details are:

CentOS 6.5
Ruby 1.9.3-p551
Rails 4.2.1

The error message from production.log is as follows:

_Starting Download Plugin for Redmine
Started GET "/" for 192.168.1.10 at 2015-06-22 12:20:41 +0100
Processing by WelcomeController#index as HTML
Completed 500 Internal Server Error in 17ms (ActiveRecord: 1.8ms)

ArgumentError (comparison of Time with BigDecimal failed):
app/models/setting.rb:187:in `<='
app/models/setting.rb:187:in `check_cache'
app/controllers/application_controller.rb:100:in `user_setup'
_

Any help would be greatly appreciated as I have been stuck on this a long time and cannot find any similar issues online.

Thanks.
