A user recently reported that a thread on my site started returning an Internal Server Error last night. The thread is in Q&A format, but besides that it’s normal. I dont know what’s causing this. There’s another Q&A topic here which works fine.

Check the /logs page for the backtrace of the error 500.

I see this. 35 Deprecation notice: `SiteSetting.secure_media` has been deprecated. Please use `SiteSetting.secure_uploads` instead.

[תמונה] Pyx : plugins/discourse-question-answer/app/serializers/question_answer_comment_serializer.rb:17:in `name' That looks like a bug in the discourse-question-answer plugin. I think if you remove that plugin (or perhaps use safe mode) that error will go away.

There was an issue recently where having the old discourse-feature-voting git along with post-voting in your app.yml would cause error 500 for the whole site. This is slightly different though, but may still be worth a check? If so, could you try updating your app.yml with the discourse-topic-voting and discourse-post-voting links and see if that helps?
