The software powering this discussion forum encountered an unexpected problem

(Bernard Sadaka (SDKAAA)) #1

We are facing this problem on our discourse instance:

Oops

The software powering this discussion forum encountered an unexpected problem. We apologize for the inconvenience.

Detailed information about the error was logged, and an automatic notification generated. We’ll take a look at it.

No further action is necessary. However, if the error condition persists, you can provide additional detail, including steps to reproduce the error, by posting a discussion topic in the site’s feedback category.

Anyone else facing it? and how to solve it?

Examine the error log by running the below commands (on your server as root)

cd /var/discourse
tail shared/standalone/log/rails/production.log.

Do whatever you think happened to cause the error. If that message shows up again go and paste the full error message from that log file (remove sensitive stuff like passwords and cookies).

You can just go to /logs in the URL btw (a bit quicker than logging in via terminal, but you’ll soon need to do that!)

Do you see this error?:

StandardError (Attempting to access a non preloaded custom field, this is disallowed to prevent N+1 queries.) /var/www/discourse/app/models/concerns/has_custom_fields.rb:158:in []

This has been happening to a lot of sites recently due to a core change which is causing several plugins to break the build. Many plugins have been updated to fix this including Topic List Previews, Events Plugin, Discourse-Solved and Custom Layouts plugins.

First I would perform a complete rebuild to pick up all the updates, then if that doesn’t resolve it I would remove all plugins that don’t have explicit fixes for this and rebuild.

Indeed it seems there is also a problem in the discourse-locations plugin?

I’m not qualified to comment wrt to the Locations Plugin, but suspect the data will still be there and return as have noticed that behaviour with many other plugins. Raise with angus.
