Lock screen wallpaper can not be changed...

[Svenchen]

Hi,
when I try to change the lock screen wallpaper in settings/wallpaper it says "picture can not be loaded". It doesn't matter which source I use, system wallpaper or own pictures from my gallery. I use the standard theme, but Apex Launcher instead of MIUI.
Can anyone help?

change launcher for miui, set wallpaper, change back to your launcher.

Thanks, that worked.
