500 error when creating a new category

[kean-stump-tfs]

I created a new category with no problems. Creating a second category throws this:

Anything else you need to know?

Are you 100% sure that you took the most current version? That error sounds awfully familiar to one, which was recently fixed. Also, the 'new' method of the IssueCategoriesController is overridden by the plugin, which shouldn't allow Redmine to call the original 'new' method as the last line in your log indicates.

Did you apply any changes to your Redmine installation (codewise) without properly restarting the application and/or using the development environment? This sometimes unloads the patches.

Hi have the same problem with today version.
I clone the repository and move the folder to my plugins directory. Then I run a db plugins migration.

I'm pretty sure I pulled the most current version. Tomorrow I'll walk through the install again on a clone of our server, make sure I'm doing the right thing.

Please pull the most current version again as some changes have been merged which may fix this. Thanks.

I too have had the same issue today. I get a 500 error when trying to create a new issue. Same error message as above.

Ruby 1.8.7
Redmine 2.3.1

I have created new categories on a clean install of 2.4.4 with the latest head version and had no issues.
