Discourse installs have become unresponsive

[joseph]

@eddowding looks like something went wrong in the assets (there are some browser errors). have you tried restarting the app (this will rebuild assets)?

[eddowding]

Yep, I did that before submitting. I gave it another kick and the same outcome: here's another example: https://meta.southpole.one

@eddowding thanks, as a last check.... If you go to Location tab of discourse and click save without making changes, is the result the same ? (The difference is that restart does incremental build of the assets. When you change Location it will do a full rebuild of assets).

Do you also have any plugins installed? You have to update these manually.

[eddowding]

Nice idea, but same outcome.

The plugins might be out of date. Can I update from the CLI?

[joseph]

@eddowding you can just delete the plugins from the plugins folder and restart the app. Make sure you have a make an app backup before you do this, just to be safe. If that also doesn't work, can you write to us at support@cloudron.io ?

[eddowding]

Will all the settings be gone, then? I'd rather just update them.. is that not possible?

[eddowding]

I've emptied the entire plugins directory and it's still not working alas.

[joseph]

@eddowding good question. I am guessing settings won't be gone from database. A simialr question was asked in https://meta.discourse.org/t/how-to-completely-uninstall-remove-a-plugin/55034/ but nothing conclusive there

[joseph]

@eddowding are you trying to rebuild the forum? the initial links don't work anymore... But as said, we can try to debug it if you can give us access and mail support@

This was sorted out on support. Discourse has a database table called javascript_caches which holds on to some old theme assets. Just removing the entries in that table makes the site load again.

I got this hint from various threads.

• I think this was a bug in some old releases. https://github.com/discourse/discourse/pull/16669 is the fix upstream
• https://meta.discourse.org/t/uncaught-in-promise-error-could-not-find-module-discourse-widgets-search-menu-imported-from-discourse-theme-70-widgets-search-banner/300297 is the browser error
• https://meta.discourse.org/t/using-safe-mode-to-troubleshoot-issues-with-themes-and-plugins/53504 (there is a /?safe_mode=no_themes,no_plugins )
