Client illegaly manipulated 2016 client files

[fido67]

Hello i've tried to create in item by adding him in : itemInfo , itemInfoServer and ItemViewInfo ( wich is in client side , i put also itemInfo in client side and serverside) , when i launch my modified client i have : client has been illegally manipulated.
If i use a vanilla client i have same error.
If I modify only itemViewInfo in client to change color of an item I have the same error with a vanilla server. It seems that something in client need to be modify to allow modification , do you know what is this ?

Version?

If its 2015/2016 you should make sure the View Folder of the 9data/shine folder MATCHES client side.
