“Hack attempt” issue for edit catalog

[design160]

I post bug here:
In my back office of my site, I can add new products or catelogries, but when I edit them, will see “Hack attempt”:
1. edit catagories: even no any change, just click save, it will be “Hack attempt”, can not chanage anything;
2. edit products: change name or price,
it will be “Hack attempt”, but in front end, the name has no change, the price had changed.
Pls help for it. Thanks!
