Redmine 3.x compatibility?

[hameno]

It seems this plugin is not compatible with Redmine 3.x, any plans to update/add support?

[fbender]

I'd be interested in this as well. Support for 2.x may end this year.

When I installed, it showed error below.

Check #7 for a solution to both the deface dependency lock (old deface requires old rails, which new redmine doesn't support) and fixes changes to the api of deface that caused the theme preferences drop down to not show up.
Unfortunately, maintainers here seem idle, but you can clone directly from https://github.com/seyedmmousavi/redmine_user_specific_theme.

I also had a dependency issue with mime-types using Redmine 3.2.0 (it didn't restrict version to <3 which requires ruby3), this was resolved by updating to Redmine 3.2.1 (released 2016-03-13, https://www.redmine.org/news/105).

Thanks to Undev for the plugin.
