webgui not working, 403 Forbidden nginx

I've got a Pi3 with OMV4 on it sharing out some samba shares to my network that I use to take backups on. Just built it a few days ago, and it's been running fine, no issues. Today I got on it to just make a little script to alert me if my backups failed. Which involved installing msmtp. That's pretty much all I did. Now I can't get to the webgui, and it gives me a 403 Forbidden error. I tried running omv-firstaid, but get command not found (running as root). When I tail the openmediavault-webui_error.log, it shows a bunch of the following error:

*1 directory index of "/var/www/openmediavault/" is forbidden, client: ::ffff:127.0.0.1, server: openmediavault-webgui, request: "GET / HTTP/1.1", host: "127.0.0.1"

Anyone know what the heck might have happened? I've run apt update and apt upgrade, and rebooted, but to no avail. I can't seem to get the web gui to load.

Maybe someone could give me a sample listing of what should be in /var/www/openmediavault, and maybe the permissions? Is that where the web root should be? It seems to me there should be more files in there. The only thing I have in there is a js directory. This is literally the only thing in /var/www/openmediavault:

./js/omv/util/i18nDict.js

Did some crap get wiped out? Do I need to start over and reinstall?

Zitat von gderf

A lot of stuff is missing. List attached.

Wow wft. How in the world would that happen lol. Well I suppose it wold be easiest to reinstall. Unless you know of some packages that I can just install that might put it all back in place?

Thanks for providing that list, very helpful.

Well, I thought that might have done it, it got me to the login page. Although with that much missing, I would imagine a bug would rear it's ugly head eventually, so figured I might just have to start over anyway. Luckily, it's a pretty base install. I install buster lite, install OMV, change a couple of basic settings, and set up some user shares. Really I could do what I'm doing without OMV, I'm mostly using it for it's ease of administering samba shares, and a few of the little tools. But I do like OMV as a nice front end management system that I can use without having to VNC into the machine or anything. Gives me a way to administer the box headless. So my reinstall won't take long. Thanks for the help. Here's the error I got after the reinstall if you're curious:
