InfoBar - My InforBar stack worked the first time, why is it not now?

The reason this is happening, is because you have the settings set to view at a low number of times, your computer cache remembers the number of times it has seen a page so if you reach that number, you will not see it. You need to change the settings in the stacks settings. If you change it to 0, everytime you go to the page, you will see the InfoBar.
