Hello. Have a problem. Button "See more" goes to Error page, some of 12 articles go to k2 items and some of them to Blog. How to solve this problem? Thanks.
"See more" does not work dynamicaly, You need to put the actual url in NSP settings first.
Please make sure all the items are in a category and that You have a menu item added to menu with a K2 category type of this category. This is so called landing page and thanks to that joomla will know where to open articles.
