I too got the web-push Ruby error. Normal forum, no custom plugins.
web-push-3.0.0 requires ruby version >= 3.0, which is incompatible with the
current version, 2.7.6
There have been times previously when it’s said that it must be upgraded via command line. Maybe that option could be enabled now for whichever version is causing this issue?
Edit: Oh, it does actually say that!
The issue is that when you do a docker_manager update and then just click the tab on the top rather than refreshing the page. So could it be changed to refresh via HTTP rather than just changing tabs with JS?
