Redmine

I updated from redmine 0.7 to 1.0.3 which worked fine on a test machine - except for some smaller problems.

But the real issue is that all counters don't seem to work. See attached screenshot.
e.g. instead of

Bug: 23 open / 546

Bug: {{count}} open / {{total}}

Also happens for other fields all over redmine. I also tried redmine 1.0.4 with the same result.

What could be the reason? Any help appreciated!
