That’s good to know, I never heard about that issue. The plugin you linked to hasn’t been updated in over 2 years so that may be the reason it’s not working properly (since there has been a lot of changes to WordPress from the time it was released/updated).
I’ll send a note to a few devs I know to see if they have any ideas. It would probably be a good idea to post in the WP forums to see if any of them have went through the same issue and have a solution. If they have a solution I’d love to know so we can pass it along in case anyone else runs into a similar situation.
