Default Post thumbnails not showing up?

[imported_renee]

I don't know why the photo in my recent blog post (not a property post) is not showing up like the others are? I created the post like my other posts, and the image was in my media library. Nothing special here. http://landrushnow.com

The cache solution another member posted (below) didn't work either:

wp-content / themes / agentpress_1.02 / tools /cache

Make sure you have your "cache" folder permissions set to "writeable". When my thumbnails weren't showing up (TimThumb is cool, but it's a pain) this is what worked for me.

The person that helps me w/my site told me: "there was no cache folder in this version of Agentpress. I created one anyway and set it to 777 but it did not work".

Please help. This shouldn't be so difficult! Thank you!!
