Dashboard empty since upgradeto 2.5.0

[ced (Cédric Krier)]

Since the update to 2.5.0, our dashboard does not display any graph at all. The settings of dashboard are set to default with the usual page_view_total_reqs, visits etc.
I see no error in the JS console nor the Error Logs.
Is there something new to activate?

Silly question to ask, but have you cleared the cache in your web browser since the upgrade? Which browser are you using? And is that the only page that is not working?

[Stephen]

Is that for one staff user, or all?

Are you using a supported browser?

There have been similar issues in the past using browsers such as Brave when device recognition (fingerprinting) is turned on.

Yes, I even tried different browsers: Firefox and Chrome.

@lankma

Which browser are you using?

I use Firefox 77.0.1

@Stephen

Is that for one staff user, or all?

It is at least happening to 3 different users.

Have you tried in safe mode?

[ced (Cédric Krier)]

How do you activate the 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. To access safe mode go to: http://your-site-name/safe-mode for example this is the safe mode for our demo site: https://try.discourse.org/safe-mode [safe mode options] [safe mode is enabled] To exit safe mode simply close your browser tab When entering safe mode you can select between: Disable all themes and theme-components …

I tried in safe mode and I got the same result: no graph.

[codinghorror (Jeff Atwood)]

Have you tried disabling all third party plugins? That’d be the next step. We have no repro of this problem anywhere on our hosting.

[ced (Cédric Krier)]

With all plugins disabled, still no graph.

[codinghorror (Jeff Atwood)]

I’m not sure. We have no repro on any of our instances, but we run the latest beta. You could try updating to latest beta, which is how all our hosted customers run.

[ced (Cédric Krier)]

We do not want to run on beta because we prefer low maintenance and stability.
Do you have any idea where to look at? Because I can not find any error logged.

[Stephen]

That perception is what makes those three release names so problematic.

The vast majority of sites run on tests-passed. There are far fewer sites on beta and stable. A lot of developer focus is on the tests-passed builds, with fixes arriving in hours rather than days. If the other releases are also affected, those fixes are only subsequently backported, and even then not always.

That’s before you dig into the other issues faced by stable, third-party plugins are a particularly good example as they’re usually updated to support tests-passed and occasionally break compatibility with stable in the process.

After doing a full rebuild with ./launcher rebuild app, the dashboard is back.
