Latest beta update (2.7.0b7) gone wrong

[tremblap (Pierre Alexandre)]

Hello

I am the happy user of this platform and so far, all updates were seamless (using a docker droplet at digital ocean, keeping the updates on there, and updating discourse and the docker via the /admin pane in discourse)

Except today. All content disappeared. So I rebooted the server. I was locked out, and couln’t log back in: I get the greyed page but not the login entry boxes.

I went on the server, pulled the git and rebuilt the app, same problem.

Now I’m a bit stuck. I would like to revert to the previous beta I had 2.7.0, or to go forward and sort this install, but because I’m locked out, I don’t know how/where to look. I’ve search meta but cannot find a troubleshooting guide for upgrade-gone-wrong…

Help?

The issue is most likely caused by an incompatible theme or plugin. Have you tried out safe-mode?

Use Safe Mode to troubleshoot issues with themes and plugins

Discourse has a “JavaScript Safe Mode”, where any user can use to isolate the root cause of a JavaScript issue caused by plugins, themes or theme components.

update: as I was writing this, and read about JS earlier I asked a colleague who managed to log in (by turning css off) and deactivated our sole plugin, for which there is already a PR it seems: There’s already a PR https://github.com/Daemonite/discourse-clipboard/pull/5

It might help someone

Great, glad to hear things are working again. That theme component looks like it’s no longer receiving updates. You might be interested in this, which provides similar functionality:

Copy codeblock contents to clipboard

Now live in core Discourse is the ability to show a copy button for codeblocks! import { createWidget } from 'discourse/widgets/widget'; createWidget('my-widget', { tagName: 'div.hello', html() { return "hello world"; } }); This feature is off by default, but if your community could benefit from it, you can turn it on by enabling the show copy button on codeblocks site setting. Some notes about the feature: The button shows up on pre > code codeblocks, but not inline, …

@david

Have you tried out safe-mode?

oh this is genius. Is there a troubleshooting page where I could have learnt about this? It is great! So much to learn… thanks!
