I have multiple K2 items created, and the items are sorted into different categories. When the pages were created, I just copied the settings from the previous page to the new page, so every page is standard. Some of the article content is not showing up, but the title is visible. Other articles are working properly. If all of the articles have the same settings, what is causing the problem?

Note: the content shows up on the back-end for all articles. The front-end only shows content for some of the articles.

sounds to me like it's an "introtext" issue enabled or disabled and possibly if you copied content, you need to redo the "read more" to define the introtext. To see the whole article the readmore has to engage and the introtext has to be off. I find setting all those in categories works better than individual articles unless you vary it a lot

Thank you. I removed the read more previously, and once I added it back again the content was showing.
