• Start the server, login and close the server
• Install the latest version (v2.0.0-pre6 right now)
• Start the server and notice the following error in the server console:

Missing error handler on `socket`.

I can't figure out why but I am now able to log in while none of my other users are. I can view all of my custom css and highlights.

Same bug for me.
I can't log. Any workaround?

@toxinu, there is a bug fix under review: #570.
In the meantime, you can either log in with a different browser, or in private browsing, or by emptying your browser cache (but careful, that will delete your custom CSS if you have some, as well as settings).

@astorije, browser cache deleted. Thank you! 👍
