Internal Error

[ElskerDane]

I believe that I have successfully installed your plugin; however, when I attempt to import a CSV file (even the sample file), I get an internal error.

My environment is:
Redmine 3.0.3, Ruby 2.0.0, Rails 4.2, Windows 7

This is the error I see in my production log:

I am experiencing the same problem. I was able to install the plugin and get it up and running but I am not able to import a template. I have the same error message above.
The environment I am using is a bitnami install with the following parameters:
Environment:
Redmine version 3.0.3.stable
Ruby version 2.0.0-p645 (2015-04-13) [i386-mingw32]
Rails version 4.2.1
Environment production
Database adapter Mysql2
SCM:
Subversion 1.8.11
Git 1.9.5
Filesystem
Redmine plugins:
csv_import_issues 0.0.2

I believe the problem lies with an incompatibility between paperclip 3.5.2 and Rails 4.2. I've tried newer versions of paperclip without success. Any help would be appreciated.

Same here:

Environment:
Redmine version 3.0.3.stable
Ruby version 2.0.0-p645 (2015-04-13) [x86_64-linux]
Rails version 4.2.1
Environment production
Database adapter Mysql2
SCM:
Subversion 1.8.13
Git 1.9.5
Filesystem
Redmine plugins:
csv_import_issues 0.0.2
redmine_agile 1.3.9

I'm completely new to redmine, ruby and such (yet not to programming;), so I can't provide any additional ideas.
