What do i have to edit so this error stops coming? It laggs my server.

If I'm not mistaken that is a 0.4 function, so at public 0.3s won't work.

The error is because the function is badly written or the function is not being loaded(or does not exist) -getItemParent- for that distro

Thats not the problem. Bump!
