Internal error when updating e-mail notification settings

Added by Miguel Rentes about 2 years ago

Hi everyone,

I installed Redmine stable on a Debian 9 server from apt, and was configuring the e-mail notification settings. I copied configuration.yml.example and changed it to configuration.yml with the following contents:

# default configuration options for all environments
      delivery_method: :smtp
        enable_starttls_auto: true
        address: "" 
        port: 587
        authentication: :login
        domain: '<my domain>'
        user_name: '<my user>'
        password: '<my password>'

I tested sending e-mails from redmine and it works perfectly. The problem is when I change any setting from the E-mail Notification setting page. Any change on any field will result in the following error:

Started POST "/redmine/settings/edit?tab=notifications" for <ommited> at 2018-07-25 16:53:17 +0100

Did you mean?  to_s):

  app/controllers/settings_controller.rb:36:in `edit'
  lib/redmine/sudo_mode.rb:63:in `sudo_mode'

I am using Redmine in Portuguese, hence the "Guardar" action (which means "Save" in English btw). I don't know what can I do to fix this, please help.
My current environment settings are as follows:

  Redmine version                3.3.1.stable
  Ruby version                   2.3.3-p222 (2016-11-21) [x86_64-linux-gnu]
  Rails version        
  Environment                    production
  Database adapter               PostgreSQL
  Git                            2.11.0
Redmine plugins:
  no plugin installed

Thank you.

I managed to solve this problem by backing up the database, dropping it, completely remove redmine and install it again. Then I inserted the data from the database backup for the tables I needed (projects, issues, etc.) and everything works great now.
