[anhtuan206]

I got the same error on redmine 3.3.0
Where did you get the log?

[byZARE]

Hey i got it in the bitnami redmine log
C:\Bitnami\redmine-3.3.0-1\apps\redmine\htdocs\log\production.log

[octoquad]

I'm getting this as well in 3.3.0. The plugin still works if there are active accounts that were added in 3.2.x, but managing accounts is not possible any more. View and Edit don't seem to work due to the error.

Duplicate of issue #21. There is already a pull request to fix it: #22

[dskibarko]

Dear Developers, then issue will be fixed?

[octoquad]

As I mentioned in #22, this fix has been applied and is also available for Redmine 4.0.x at https://github.com/octoquad/redmine_email_fetcher.

I'm not sure if there are still active Redmine 3.3.x users, but perhaps I can backport this fix to 0.3.x release.
