403 Forbidden - Web UI - Please Help!

I'm getting 403 Forbidden on the Web UI.

I was trying to set up sendmail via CLI for another service (Greyhole): https://www.fosstechnix.com/co…-emails-using-gmail-smtp/

I received a couple of errors which led me to this page: https://alexhunt86.wordpress.c…world-writable-directory/

I ran the suggested commands...

#chmod go-w /

#chmod go-w /etc

#chmod go-w /etc/mail

#service sendmail restart

nginx OMV error log:

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"

And I think that's what broke the OMV GUI.

Any ideas? I guess I need to reset the permissions correctly. Feeling a bit stupid for running those without thinking it through.

As a side omv-firstaid: command not found

What the hell. The only file in /var/www/openmediavault/ is /var/www/openmediavault/js/omv/util/i18nDict.js

Seems to be the same as this person.

webgui not working, 403 Forbidden nginx

Reinstalling OMV using

sudo apt-get install --reinstall openmediavault

Has brought back the GUI login screen but I still can't log in

OMV\Rpc\Exception: Failed to connect to socket: Connection refused in /usr/share/php/openmediavault/rpc/rpc.inc:141

Though, now I can run omv-firstaid.

omv-engined -f -d

...allows me to log in! from this post

Failed to connect to socket: Connection refused

Though they updated thier kernel and the instructions don't work for me.

Went down a rabbit hole of posts and Googling how to update Kernel. Just ended up with multi page threads on this site and non OMV sites with instructions that were outdated or didn't work for me. Fresh installed the entire OMV.
