featured content images not showing

[tomclark]

I'm sure it must be something quite simple, but I've been trying to get the featured content images to appear for 6 straight hours! I've searched the forums for related threads, read the tutorial, visited the plug-un website, removed and re-installed the theme and plug-ins, changed the setting to find the posts by category and then post number . There is an outline of a box that appears where the image is supposed to be but nothing else. The images do appear on the individual post page (I added the images to to post area as well as the custom fields box.

I just purchased the themes, and am experimenting on an unused domain: http://individualdentalplans.us

The only thing I was not able to do was to make sure the permissions on the agent_30/tools/cache directory is set to CHMOD 777. I have no idea how to do this, so maybe that is the problem?

Thanks in advance
