Error logs empty after upgrade

Product Support

AI-generated summary

Users reported that after upgrading to Discourse version 3.1.0.beta3, their error logs became empty — both old entries and new events were missing. md-misko confirmed this on two separate instances and noted recurring console errors on the /logs page, including a 404 for messages.json. JammyDodger initially reported no issues on their test site, suggesting the logs appeared intact, possibly due to a different caching state or environment. david suspected a cached JavaScript file was causing the issue and advised a full browser restart. md-misko confirmed the fix: a hard refresh (Ctrl+Shift+R) or manually clearing Chrome’s cache (including on Android) resolved the problem, indicating the issue was client-side caching rather than a server or database error. This suggests the upgrade introduced a frontend asset change that older cached versions failed to handle correctly.

Version 3.1.0.beta3, all previous log entries are missing, new events are not logged.

Same issue on two updated instances.

I updated my test site to 3.1.0.beta3 this morning and my /logs history still appears to be intact? I think I also have some deprecation warnings from after the upgrade too.

Am I looking in the right spot?

I have lots of recurring console errors on the /logs page (no errors on the main forum page).

Please can you try completely quitting your browser and then reopening? I think it’s likely that you have a cached version of the /logs javascript

That was it, thanks. Browser reopening didn’t work, but hard refresh did (and clearing Chrome cache on Android).
