Hi, i fallow the instructions from here k2community.joomlaworks.gr/notes/Templating_in_K2
and when i make a menu item and Choose k2 category i get an error,

JFolder::folder: Path is not a folder

Warning: Invalid argument supplied for foreach() in \administrator\components\com_k2\elements\template.php

and in the template selection i dont see any of the templates

Hi. Please check again that you are following the instructions and that your folder name is safe ( no spaces or special characters ).

i found my problem, i accidentally move the folder templates instead copy it.
