Solution for error 'OpenVPN error: PolarSSL: ca certificate is undefined'

Mac user solution for Openvpn error [OpenVPN error: PolarSSL: ca certificate is undefined].

I recently download this Openvpn for mac and while importing my configuration file I encounter this problem. So, I search to google how to solved this problem, till I came out with this simple solution.

Before importing .ovpn file, first edit your .ovpn file using a file editor for MAC, for me I use CotEditor.

This is the example of my .ovpn file

keepalive 1 180
resolv-retry infinite
redirect-gateway def1
