I have a K2 content module positioned in a side bar that is set up to show articles from a specific category. I had everything set up correctly but after changing some configurations, I see the text of the articles twice. I realize that this is a configuration issue but after creating a new article, the text does not show. When i correct this, it shows twice in the older articles.
Which configuration do I want? The category config or the parameter config, both, or item or all 3?

I have done some searching about this and I do not have any contacts listed at all so I doubt it is the double contact issue. I have also checked the template and it also happens in default Joomla templates.

Update: (failed) deleted all items, module, and category affected. Rebuild with default settings, all is back to normal. It is unfortunate that the configurations can be mixed in such a way as to find oneself unable to synchronize them again. How about a "sync settings button"?

This is killing me. The content shows twice in the older articles after I post a new one in a K2 content module in the right column. The first article was great but when I made another, that first article now shows the content (alone) twice. The headers are fine but the actual written content repeats after the "add a comment" link.

OK, I turn off intro text in the module settings and the latest article loses all text and the older one shows just once. How do I synch these? Or why does it cause them to repeat?

Have you set the same text in introtext and fulltext?

Where do I "set the text"? I simply c&p text into the K2 item WYSIWYG editor.

This is not to say that I haven't changed the configurations. Perhaps if I knew which configs needed to be set and how. It's all very confusing as the layers are under layers of configuration.

Started using native joomla articles for that one mod and it's working well. I will use k2 items where they still seem to work for me. Unless anyone can tell me how to reset the K2 config or uninstall K2 without losing all of my work and then re-installing fresh.

Are you using two editors?

One for introtext and one for fulltext?
This issue can also be caused by your template. Is it working properly with the default template?

No, and No. Other templates like Beez show the same problem and I am using the JCE only.

By two editors I mean two seperate editor windows, not two separate editors.
Also which version of K2 and Joomla! are you using?

Just saw this post.
Maybe you resolved your pb (it is an old one) but in case not
==> I had the same problem (using K2 2.6.9) ==> I noticed that it showed the text twice every-time I was not add a "Read More".
If you insert a "Read More" it is solved
