After disabling all the plugins and rebuilding, there is just this error:
Failed to load โhttps://forum.code-operative.co.uk/assets/vendor/fontawesome/fonts/fontawesome-webfont.woff2?v=4.7.0โ. A ServiceWorker intercepted the request and encountered an unexpected error.
Re-enabling these plug-ins:
nodebb-plugin-markdown
nodebb-plugin-mentions
Then I see 404s on /plugins/nodebb-plugin-markdown/styles/railscasts.css. Seems to be a bug in the markdown plugin, I filed a bug here:
I also get more occasional .ttf//.woff errors as above. And lots of [benchmark] warnings in the server logs, I think these can be ignored.
Renabling these seem to go without faults:
nodebb-plugin-composer-default
nodebb-plugin-dbsearch
nodebb-widget-essentials
However, nodebb-plugin-private-forum introduces errors, when visiting anonymously.
https://github.com/LM1LC3N7/nodebb-plugin-private-forum/issues/2
Finally, installing nodebb-plugin-poll doesn't (so far) seem to create any errors....
Will keep an eye on things. There were some other plug-ins (code-button, emoji-related) which I didn't consider important enough to re-enable.
