HI,
I'm a very noob user and i may have messed things up pretty good. I flashed Open WRT to my dlink DIR-878 router and was attempting to connect through NordVPN using the openvpn function... I followed the tutorial in the Nord support pages and couldn't get it to work... i gave up and attempted to reverse what i had done. I removed the VPN instance that i had created then i removed the system software that i had installed:
openvpn-openssl
ip-full
luci-app-openvpn
Now when i try to access the router through 192.168.1.1 i can get to the log in but once i enter the user and password i get an error message that looks bad....
here's the text...
Error

Seems concerning.... any ideas as to how one might start again?
cheers
There can be a number of causes... sometimes it's a syntax error.
Let's take a look at the configs and see if we can identify anything (and if not, you can always reset and start over).
Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button (red circle; this works best in the 'Markdown' composer view in the blue oval):
Remember to redact passwords, VPN keys, MAC addresses and any public IP addresses you may have:
ubus call system board
cat /etc/config/network
cat /etc/config/wireless
cat /etc/config/dhcp
cat /etc/config/firewall
cat /etc/config/openvpn
Also worth noting -- it seems that Nord offers WireGuard connectivity... it's much easier to setup and also far more performant. I'd recommend that path instead of OpenVPN (unless there is a specific reason you want/need to use OpenVPN).
Reinstall luci-compat package, it got uninstalled as a dependency to luci-app-openvpn.

Thanks for the reply, I'm not sure how I can go about doing that as I can't get into the admin. As soon as I log in I get the error message? Is there a way to do it another way?
mostly defaults here, so no errors in the config that I can see.
cheers,
Is there a way I can re-install the luci-compat package without having access to the admin menu?
Login over ssh again and run:
opkg update
opkg install luci-compat
