Did you check the admin for the Masonry module? There are multiple ways to order and output the articles.
Thank you for the response, but there are multiple articles in all of my categories. The previous or next article do not follow the category or ID sequence. Please try navigating the site to see what I am saying:
http://biggscardosa.com/home/index.phpI'm not sure without taking a look first hand in your admin but this is all Joomla core stuff. Our templates don't modify or touch any of the Joomla core functions and how articles display, etc. We just style how they are output with CSS.
