Not urgent as I don’t use the Elections plugin - but there appears to be an error. I wonder if this is the same error reported by @usulrasolas’s users?
Issue
Server error 500 when editing any post - even though the posts in question are nothing to do with elections AND the Elections plugin is actually disabled.

I’m using the latest tests-passed version of Discourse (v2.3.0.beta2 +157) and the latest version of the Elections plugin.
I’ve confirmed that removing the elections plugin now allows users to edit their posts.
It looks like a) the plugin should check if it is enabled in the poll_edits.rb code - or maybe in plugin.rb and b) there might be an issue caused by the poll refactoring in 2.2 where polls were moved from post_custom_field to their own tables? That said I’d assumed that code that worked with the old tables would still work for historic polls?
Background
I mention the following in case it is important, but may be unrelated.
I installed the Elections Plugin a while ago but after some initial testing I didn’t use it - planned to in the future but just disabled it.
Over the last month or so topics on our forum would ‘die’ whereby the footer of the topic would disappear and scrolling to the bottom would simply show the last post in the topic.
Any updates to that topic would no longer show ‘live’ and the console showed that the message bus had failed but no clue as to what had caused the failure.
To track down where that bug came from I’ve been in the process of disabling and enabling lots of plugins on our live community.
I’d identified that I could get the forum running as expected by removing from app.yml (not just disabling) the discourse-ratings and discourse-elections plugins.
I still wanted to find out exactly where the issue was so I re-added those two plugins to the app.yml but left them disabled.
I was hoping to see my original ‘dying topic’ bug reappear but instead, at this point I have only seen this 500 error when editing posts.
I don’t know why this error has suddenly appeared now as before we could edit posts with ostensibly the same configuration.
