Thanks @Stephen I tried to reproduce the error in both safe-mode and out of safe-mode, but unfortunately I could not. I’m suspicious that it only happens when a user is logged-out. Perhaps when I logged in it reset cache/etc. and therefore “fixed” the error.
I forgot to mention, here’s how the error occurred in the first place:
- on Slack App, we use the Discourse integration. I clicked a topic link from the integration bot, which opens in my Chrome browser on mobile.
- I am not logged in on my Chrome browser. I received the blank page mentioned above.
I have the Discourse Hub app on my phone. Typically I open this directly to access the forum and topics.
