Hi. Go to menu link and check it's settings again. Ensure that the sum of Leading, Primary, Secondary and links is more than 2. Otherwise K2 will split the page and display pagination. Other things to check are the items ( and categories ) access level, language, start and finish publishing dates. Other things that may cause this may be custom template overrides or 3rd party K2 plugins. Finally, as a side note, you need to update both your Joomla! and K2 installations.
