Before I completely flatten my face against the top of my desk, can anyone give me any hints at all how the following might be occurring. Our dev site is at www,thebigfix.org .. cache is currently turned off so we know it's loading slowly. We are using K2 for the main content categories but I also have about 4 Joomla articles to separate the admin stuff etc. When we turn 'Conservative caching' on though, we're getting the issue you can see in the screenshot ie. it is drawing in a Joomla article to all the K2 category positions on the front page. Cache plugin is turned on.

Hello,

This is a really strange issue indeed. Are you using a K2 plugin or a module in that position?

Thanks Krikor,
I am using only Joomla modules so I'm wondering whether it is a jquery or CSS issue. Turning off K2 CSS and jquery and leaving the template settings as shown makes the problem worse.

The only K2 plugins are:

It is definitely not a jQuery or a CSS issue. My bet would be on the template or its framework.
