hi i'm new with k2
when i try to make a menu item with "Item edit form" type it gives me 404 not found page
i thought it might be from the template and i installed pure joomla and did the same actions an it gives me the same erroe
this is the link of the button
index.php?option=com_k2&view=item&layout=itemform
and i'm logged in with super user and user group administrator
thanks in advance

Make sure that you have enabled Frontend Editing through K2 Parameters and a K2 User group where your user has the right permissions to add/edit items and assign this user to the K2 User Group.
