Hello,

I have several problems when i try to change a item or selected items:

1- If i try to reorder items by moving them, list of items break and all get stuck
2- If i select one or more items to publish the publish button dont have any action, to publish i have open the item and check publish radio button one by one...
3- I cant add option in products, field for add optino dont search anything

anyone can help me? Its seems a kind of conflict but i dont figure out.

This is most likely a JS conflict.

This means, that you are using K2Store, right?
If yes then the issue is with K2Store. You should address this issue to the K2Store devs.
