Weird! Try running `sudo /var/discourse/launcher rebuild app` on your server – it most likely will fix your issue, and also update Discourse in the process 🙂

Will this reset everything? What’s the impact?

It will re-create the Docker container with Discourse, but keep all your user data (which is stored outside of the container). You should expect about 5 minutes of downtime, nothing worse 🙂

This is a legit bug @tgxworld, I get a 500 error on [discourse.codinghorror.com](http://discourse.codinghorror.com) when in incognito mode, attempting to access the /admin/upgrade – and that is on latest too.
