There is a little box on the left side just below the title showing the page load times in milliseconds. I only see this on my discourse site. I was thinking that should be turned off, that maybe I turned it on when installing. Then I realized it only happens when logged in as an admin. I’m ok with that. Just posting anyway in case it might help others as I didn’t find anything about it when searching.
It’s called the mini profiler and is there because you’re using the account associated with the email specified in the app.yml as developer.
Press alt+P if you want to hide it.
Good to know. Thank you!
