Thanks for writing around! I checked your site and couldn't find the post carousel anywhere, seems like you've disabled it. However I did check your setup and I see you're using an outdated version of X and Cornerstone, always make sure to update both X and Cornerstone to the latest version to avoid such conflicts and potential errors. You can find the latest version numbers here: (http://theme.co/changelog/) Then you can compare them to what's installed on your site.
If you find anything to be out of date, you can review our update guide.
Let us know how this goes!
