On Monday I showed you where the sticky post setting was. Maybe you already knew but I had quite a time locating it and thought I might not be the only one having this problem.
So, you used that setting to make a post sticky and now you’re wondering why it isn’t working properly. Well, you have to add some code to your Main Index template.
WordPress 2.7 includes a new function called Post Class, which makes it easier to style certain parts of the theme. One of the classes used with post class is sticky. So, the template doesn’t know that a sticky post even exists until this new code is added.
