I’ve seen this mentioned a few times on Meta, but I can’t find a specific topic for it. If there is one, apologies!
When I visit
/admin/upgrade the page looks like this:
Doing a “view source” reveals this:
<html><head></head><body> <h2>You are running an old version of the Discourse image.</h2> <p> Upgrades via the web UI are disabled until you run the latest image. </p> <p> To do so log in to your server using SSH and run: </p> <pre> cd /var/discourse git pull ./launcher rebuild app </pre> <p> <a href='https://meta.discourse.org/t/how-do-i-update-my-docker-image-to-latest/23325'>More info on our support site</a> </p> </body> </html>
So it looks like the HTML is being converted into html entities somewhere along the line…
