Same issue for me...

I've made some changes and it works on Redmine 3.0.2.stable.

@Helvehammer: May I ask if the mentioned modifications are really all you had to do to get it going on 3.0.2-stable. Or was there other stuff you also had to tweak - anything ...?
Reason I am asking is that I am having trouble to use this plugin on redmine 3.0.3
(see my report in issue 31 ).

• I did apply all your changes as reported above (thanks for the precise description) - but that did not solve my problem.
• I have also removed all other plugins ... but this did not help either

Can you think of any other possible reason for my problem?
Thanks for your consideration.

@hhschmidt try to restart redmine after editing files
Linux: touch /path/to/redmine/tmp/restart.txt

[dziustino]

@hhschmidt also you could try to clear redmine cache after editing the above by @Helvehammer :

cd /path/to/redmine/
rake tmp:cache:clear
rake tmp:sessions:clear
touch /path/to/redmine/tmp/restart.txt
