IP address not updating

OpenDNS is working fine until the IP address changes. I have ddclient installed. My ddclient config is:

daemon=300 # check every 300 seconds
syslog=yes # log update msgs to syslog
mail=root # mail all msgs to root
mail-failure=root # mail failed update msgs to root
pid=/var/run/ddclient.pid # record PID in file.
ssl=no

##

## OpenDNS.com account-configuration

##

protocol=dyndns2

use=web, web=myip.dnsomatic.com

ssl=no

server=updates.opendns.com

login=xxxxxxx

password=‘xxxxxx’

I've run other diagnostics with these results:

https://updates.dnsomatic.com/nic/update?hostname=home

good 67.2.38.231

https://updates.opendns.com/nic/update?hostname=home

good 67.2.38.231

My opendns homepage looks like this:

All this seems to look like there are no errors, However, ithe ip address is never updated.

If I change the ddclient.conf to add:

all.dnsomatic.com

I get these errors:

ddclient -daemon=0 -debug -verbose -noquiet
WARNING:  file /var/cache/ddclient/ddclient.cache, line 3: Invalid Value for keyword 'ip' = ''
