Greetings, an update had arrived, though I cannot recall its exact name. It typically appears second in the update panel, and it is usually imperative to update that one first before proceeding with the others. I clicked on it and initiated the update. After a while, I had to close the browser, assuming the update would continue in the background. However, since this morning, I’ve been facing a perpetual “page loading” screen. It seems to be loading, but it does not complete. Neither the admin panel nor the homepage will open. Why would this issue occur?
AI-generated summary
EchoBilisim reports that after updating a critical component (second in the update panel), their Discourse site became stuck on a perpetual “page loading” screen, affecting both the admin panel and homepage. JammyDodger initially suspected a known bug related to API versioning during Docker updates, which had since been reverted as noted. EchoBilisim attempted to resolve the issue by rebuilding the app via ./launcher rebuild app and updating Docker, but the problem persisted. JammyDodger then suggested checking Safe Mode and reviewing logs or browser console for clues. EchoBilisim confirmed the site loads successfully in Safe Mode, even after disabling all plugins and components — indicating the issue may stem from core configuration or a deeper system conflict not yet identified. Further debugging is recommended.
I think this may be another case of this bug:
If you can rebuild from the command line that should sort it. 
Just to cross-post this here, the problem commit has now been reverted:
cd /var/discourse
./launcher rebuild app
I executed these commands, yet my site persists in loading aimlessly and fails to open.
wget -qO- https://get.docker.com/ | sh
I have also utilized this, yet the outcome remains unchanged; my website continues to load incessantly without opening.
Hmm. Perhaps that wasn’t the issue (or possibly not the only issue). Let’s slip this back into your dedicated topic and see if we can debug it further.
Does your site work in safe mode? And is there anything in your /logs or browser console that may provide further information?
Indeed, such a screen has appeared.
The site opens in Safe Mode.
I have disabled all plugins and components, yet the outcome remains unchanged.
