I have installed K2, created categories, sub categories, tags, fields, field groups and sample items.

I have created menu items for K2 category view, K2 tag view and K2 Item view, but can not see any K2 content in the front-end of the site.

I have also created a joomla article and can't get it to show either. I've never seen this before and this is my 15th joomla site.

I don't get any errors, just blank pages. I can see all my content as expected in the back-end.

Caching is off.

I thought it might be a timezone problem, so I changed the created and published dates of my items and an article to 3 days ago, but it didn't help.

All K2 plugins are published.

I'm using Joomla 2.5.6
K2 v2.5.7
Web Server Apache
PHP version 5.2.17
MySQL version 5.0.92-log
Memory limit 128M

Any ideas on what else to check?

Hi. In case you are building a multilanguage site ensure that you have added content to the language you are viewing. What other extensions have you installed? Also try to enable "System Debugging" under Joomla! configuration to get any possible SQL errors.

I have the same error.

The items exists on the db but not displaying on the front end.

Do I have to uninstall / install any plug in?
