J2.5.28, K2.6.8. I imported 8000 items using K2 Import component (_http://extensions.joomla.org/extensions/extension/extension-specific/k2-extensions/import-for-k2) in 1 category. All of them goes to common RSS (index.php?option=com_k2&view=itemlist&format=feed&type=rss). But after that new articles which I add manualy in different categories goes only in category RSS (***/category.feed). Common RSS doesn`t update anymore. At the same time new articles in first (imported) category goes in category RSS and common RSS. Why?

It is better to create a hidden menu item towards all categories and name is as eg: content. This menu will render all orphan tags and users and you will have your RSS feed from that menu item.

Thank you very much!

You 're welcome Vladimir.
