I have imported my articles to K2. When I then open them as items and change the text, those changes don't show up on the front end. Did I miss a step in the import process? I clicked the Import Joomla Content button and nothing more. Any help is appreciated.

You should check your cache settings. It's possible you are seeing cached content.

I refreshed the page and still no changes appeared on the front end. I went into the joomla! quick icons and clicked "articles" and made the changes there. That did show up on the front end. Any ideas on how I make k2 my main content manager?
much thanks

Oooohhhh! I just noticed what I have been missing! My menu items are still "single article," I just changed it to "item" and that did it! I'm up against a big learning curve... thanks for offering a forum, I imagine I'll be using it regularly.

Glad to be of help,
