I recently upgraded my discourse version and all of my plugins are up to date.
After upgrade I am now getting 500 error when trying to mark a reply as solution.
Below are the error details I am getting in console.
```

do you have unofficial plugins installed? Is it working in [safe mode](https://meta.discourse.org/t/53504?silent=true) with only official plugins and themes?

Yes I do have unofficial plugin installed and I haven’t checked in safemode (I dont know how to do it :noobface:)
Though I checked logs and it showed this
`ArgumentError (unknown keyword: duration) /var/www/discourse/app/models/topic.rb:1138:in 'set_or_create_timer'`
(Backtrace if you’re interested: [https://pastebin.com/chKtDTeL.](https://pastebin.com/chKtDTeL.))
Then I went to solved settings and set auto close hours to 0 (Previous value 72) and it works now but I really want to use this feature. Any help?

just go to `/safe-mode` on your site to access [safe mode](https://meta.discourse.org/t/53504?silent=true) settings. Looks like this:

Ok someone from my team has tried this already
**·** Disabling unofficial plugins (e.g. our badges plugin) did not resolve the issue.
**·** Disabling our theme (e.g. custom JavaScript) did not resolve the issue.
**·** Disabling unofficial plugins and theme together did not resolve the issue.
Using safe-mode.
Didn’t try disabling all plugin cause you know it will disable solved also 😁

It seems related to what I found in logs. Last update made by plugin author is this

I just updated my personal site to latest and enabled the solved plugin, and it works fine for me. I am not able to replicate.

I think I got the issue. We are on stable release (Not the default tests-passed) which doesn’t have the ‘duration’ change yet.

Thankyou for looking into it, really appreciate it! I think we will just wait until the stable branch is updated to use this feature.

You’re on a specific discourse version which probably doesn’t have the feature backported. The solved plugin works fine with latest tests-passed branch so consider upgrading to that.

So if i understand, stable version is not a good version for discourse production server ???

It is Good but generally very very old and lacking new features. You should really be using tests-passed as it’s stable enough and contains all new features and performance improvements.

I made a fix yesterday. Could you update `discourse-solved` plugin and confirm if the issue is solved for you?
