New Post: Backoffice pager doesn't work

Hello,

have latest DNN release and latest NB Store module.

In backoffice catalog section, once try to browse second or third page, get a new blank page.
With FireBug see this:
NetworkError: 404 Not Found - http://mywebsite.com/Shop/Backoffice/ctl/AdminProduct/mid/417/CatID/-1/currentpage/2?SkinSrc=/DesktopModules/NB_Store/Skins/Dark/Dark"

There is way to fix this?

Thank you for support
RL
