I uploaded the plugin and used it on a new page. I inserted multiple instances of the code and everything looks great. However, comments from an entirely separate post are showing up at the bottom of my new page! The comments appear to be pulling from the post in the last thumbnail. I tried removing the last list of thumbnails, but then comments from the new last thumbnail started showing up.
I disabled comments in the wordpress settings for the page. The comments are still there! This seems like a really strange bug. You can view the issue here: http://cookieandkate.com/recipes/
Please let me know if you have any suggestions!
