I have a menu item that pulls a category listing. All of the items are marked as Leading, we're not using the secondary, etc.

I set it to show 5 per page and there is a set of buttons for pagination indicating 232 pages.

But even though clicking the buttons indicates in the url the extension ?start=5, the user is not taken to the next page.

The site is behind a firewall so I can't share a link. It's Joomla 3, with K2 2.6.8, and the T3_bs3_blank template.

Any help would be appreciated!

Make sure this is not a caching related issue.
Is the page reloading and the page changes but the content remains the same?
