its giving me the message i dont have permission but im the owner help!!!

Even as the owner admin you still have to have the permissions , for example

stacksizecontroller.setstack

Permission:stacksizecontroller.setstack (Only needed if used in-game)

Usage:stacksizecontroller.setstack <item shortname or id> <stack limit or multiplier>

Parameter #1:Shortname or ID Use stacksizecontroller.itemsearch if you need help.

Parameter #2:Stack limit or multiplier Supplying just a number like "2000" sets that as the max stack limit. Supplying a number immediately followed by an x sets a multiplier, like "20x". Entering "20 x" would cause an error.

Usage Example:stacksizecontroller.setstack generator.wind.scrap 5 (Hard limit) or stacksizecontroller.setstack wood 20x (Multiplier)
