Troubleshooting: Thumbnails and images in the “Featured” slider are broken
realestate/scripts/cache folder is chmod’ed to 777. You can do this with most ftp clients. If you’ve done this and you are getting WordPress 404 pages when trying to load the image, you may need your hosting company to update mod_security settings and/or ‘whitelist’ the TimThumb script (this is required for HostGator accounts).
The easiest way to see if it’s working properly is to follow these steps:
1) In Firefox, right click on one of the image in the left column on the home page and choose View Image.
2) If you see a WordPress 404 error page, they haven’t whitelisted the script properly.
3) Send them the URL of the timthumb.php script as well as one of the image URLs from the homepage
