I am setting up some Express VPN OVPN files on my openwrt router...I installed the OpenVPN packages etc, and I uploaded the config file from ExpressVPN with no problems. The problem is when I press 'edit' next to the file to add the password/user etc, it won't allow me to save giving me an error of: Insufficient permissions to read UCI configuration.
I setup some VPNs in Feb of this year in the same way, without any issues.
This is a new install of OpenWRT that I installed today on a new router...wondering if that might be the issue? It is a Linksys WRT3200ACM...I have 3 others of this same router already, all running OpenWRT with no issues.
