Article still showing on front page

News Show Pro GK5 ver. 1.1.3 is being used on the page, I've set the Data Source to K2 Categories.

So I only have 4 articles in that category, and only one shows up on the front page. The rest of the articles were already deleted, in both K2 and in Joomla article manager, though that shouldn't even matter.

If you click on those trashed articles, you just get a 404 error.

Is there anything I am doing wrong, or is this an issue with K2, or the template?

Do you use cache? Please try to unpublish module and create new one.

I was thinking about cache when I woke up, and I did a little looking through the back end, there are no cached items, to even delete. Not unless K2 handles cache differently. I couldn't find squat on Google on how to clear K2 cache.

When I go to Extension Manager: Manage, there are 4 items that are cache related.

System - GK Cache (Site - Plugin) and System - GK Extended Cache (Site - Plugin) These two are disabled.

Cache Manager (Administrator - Component) and System - Cache (Site - Plugin) are both protected extensions.

I don't know if this helps or not. My experience comes from J2.5 and I really haven't worked with J3 at all. It's driving me insane!!!

Well don't worry about that...I've come to the conclusion that there was a problem with the demo files. If I tried to delete a trashed K2 item, the site wouldn't load...

So I am doing things by scratch. Installed J3, then the template, then the modules/components/plug-ins as I need them.

Still having issues, but at least they should be fixable.

Please just disable all News Show Pro modules firstly - probably NSP is trying to display not existing article.
