After spending untold hours trying to get this to work properly on various sites I've given up! All formatting of pre and post text is lost every time you open the module for adjustments and has to be re-done. And no matter what I do the spacing between the w, day, month etc just turns into a bunch of unreadble symbols. This definitely need work on it. Nothing should be this hard! When I get some time I'm going to rewrite it.
Instead of spending untold hours trying to get this to work please click the support link and/or go to my forums to post bugs or ask for assistance. I am always willing to help and fix any issues that you can find.
