I can't remember a reason, but at one moment I stop to use "openvpn --mktun --dev [dev name]" command. May be it's becouse openvpn create tap0 by it self. So try to comment this lines:
for t in $tap; do
openvpn --mktun --dev $t
done
then restart a network, after then start openvpn and after it start bridge script
> openvpn configure file
