hello how can i turn it off? i dont need it

Hi, tornike,

if the item is under an inherit parameter on a category, and you want to remove all this stuff on all the items under this same category you have to configure the category like this :
Item view options / Author options / Display extend author info : Hide

If it's just for this item, you have to make this same configuration on the item's parameters.

Let me know if it's ok ;)
