It is bizarre. I have not changed any settings. Older articles in the same categories still show up fine but the new articles do not.

Whether it is in a category view or you click the title to open the article the main content does not show up.

Check out this example of this Category for Radio Shows. I made the article for World Puja Network a little while after I made the one for KLCU's Emotional Fitness show article.

Another user is making articles that were in previous newsletters under the Articles category and only some of those are showing up while others are not? I pushed the empty articles to pages 3 & 4.

It seems like it does this for a while when creating items and then works again?
