I'm still trying to learn the ins & outs of Joomla and I'm also trying to understand K2. The issue I'm having is when we create an article and say we need it to finish publishing two weeks away we put in the "Finish Publishing" field and save it. However, that date and time passes and the article is still published. Can you please help.

The finish publishing works on a localhost quickstart install for me. If you display a category from the "menu" and set the finish publishing date back, refresh the frontend, the item goes away as expected.

Are you displaying k2 from a menu or from some other method?

k2 ver 2.4.1
