AI-generated summary
The discussion is about a website, applenow.io, showing a connection error on every page. Abbas_Muhammad reported the issue, stating that the website was working fine until yesterday. pfaffman suggested that it might be a plugin issue, but Abbas_Muhammad replied that there are no non-Discourse plugins installed. After checking the logs, Abbas_Muhammad found runtime and DB errors. Abbas_Muhammad then posted the error stacktrace. pfaffman analyzed the error and concluded that it’s related to the AI plugin’s suggested topics feature, which is either broken or misconfigured. The suggested solution is to turn off the suggested topics feature in the AI plugin.
It’s probably a plugin. Comment out any non-discourse-provided plugin in your app.yml and rebuild again.
categories and users load, just not topics, so it’s probably some plugin that does something to topics.
There is no non-discourse plugin installed it was working till yesterday. goes down today only
What has changed since then? Have you upgraded? Added a theme component? What do you see in https://applenow.io/logs?
Getting Runtime error and some DB error.
Although i just upgraded the discourse yesterday or on tuesday only nothing else.
and today again as i thought its due to update

these sre the errors
It has to do with the AI plugin and its attempt to do suggested topics. The plugin is broken or misconfigured. I’d try turning off the suggested topics feature in the AI plugin and then if you can figure out what causes the error, make a bug report about that.
