Hi
can someone help me to fix the problem. If I edit an item at the front the mask/form/menu (I don't know wich will be the right expression) looks wrong. The tabs for content, pic, media and so on are away. Same as on the top and I cannot save and close the item (save will work, but I cannot leave the popup window. Sie attached pictures.
Thank for helping me.

Hello there,

If you are using overrides for the itemform.php file ( getk2.org/documentation/tutorials/174-templating-with-k2-and-the-concepts-of-sub-templates ), remove or rename the file.

Thanks Kirkor. It works.

You 're welcome :)
