Phone [Q] I have lost the Music Player Widget on lock screen, How do i get it back?

Hi All

I have looked everywhere to see if there is anything i may have done but cannot find out how this has happened, it just seems to have disappeared, I use the Samsung Galaxy S4 Music Player app, have been used to changing the track in the lock screen, but lately have noticed that this has disappeared.

I have noticed that in My (Settings / My Device / Lock Screen / Lock Screen Widgets) location, the Favorite Apps or Camera has been grayed out and i am unable to select this to be on or off.

Any help would be greatly appreciated. I hope that i am posting this in the right thread, and have tried looking on here to see if anyone else has had the same issue, but either am being stupid or i cannot see it.

Can someone delete this, as i don't think i have the privilege to. Feeling a bit stupid! have put in the Q&A Section now

Thanks for your help in advance.
