Error when disabling and re-enabling plugin

[potiuk]

First of all - great plugin.

I am using latest version of scrumbler from git (e0e14bafed11869ff0a34c1fb97a334f42ef293c). Redmine 1.3.2 stable (2e1467de92378d2cd4b723e2f0557119bcee4f10) from git.

I enabled scrumbler for a project, updated some version (set start/end date and such, moved tasks around and generally played with it a bit).

Then I disabled the plugin (disabled the module) ... All fine so far. Now when I tried to re-enable it, I got (when I press save in project's setttings with enabled scrumbler) I got internal error 500

I tried using Version.effective_date (Attribute of Class Version) and Version.due_date (Method to access Version.effective_date), which are both definded in version.rb inside Redmine-Models.

But this does not do much. It produces almost the same error as above: NoMethodError (undefined method effective_date' for #<Class:0x7f31752203c8>): (obvious since this is an attribute) ... or NoMethodError (undefined methoddue_date' for #Class:0x7fc42bbb9378): (dont know why this doesnt work) ...

Any ideas?

I've got this same problem with the same scenario.

[ridonkulous]

Is there a way to fix this via reinstallation of scrumbler? How can I deinstall scrumbler?
