I am having the same issue Jeremy. What is the fix so I can implement this as well? I just turned up my site, worldeventsandthebible.com with GoDaddy.com. The shortlinks are redirecting to the temporary domain not worldeventsandthebible.com
Any help is appreciated.
I found the answer last night. Justin is a brilliant man!
If someone finds this post in the future follow the link below and this will fix it for you. I have the current version (4.1.1) of WordPress and this plugin worked without issue.
