GUI is broken shortly after update to 11.2-U6

[Spacemarine]

I updated to 11.2-U6 a few days ago and I could boot perfectly fine and everything worked. Today I rebooted and I only get a broken GUI, which doen't allow me to log in. Firefox and Edge show the same result. The sourcecode of the GUI that's shown in the browser contains only one single line, so I guess the webserver is somehow broken. I also made sure that my browser-cache isn't the problem.

If I log in via SSH, I can't see any errors. How I can find out what went wrong an possibly fix it?

Try a forced reload (shift while clicking the reload button in the browser).

Already did that. As I said, it's not a problem of browser cache, firefox and edge show exactly the same faulty website.

Did you try a 'private mode' browser window? I see similar issues after every FreeNAS update and it's always browser cache for me.

A forced refresh of the window fixed it for me. Maybe there's something else wrong for you.

OMFG. That solved the problem. And right after it worked in the private window, it immediately worked in the non-private window also.
So if really my browsercache was the problem, I don't get why a forced reload didn't help and also why the problem was exactly the same on another browser. AND also why it worked right after the update, but stopped working a few days later...

But anyhow, thank you very much!
