photos/videos don't show in gallery app or backup topic

Hi guys

I've just moved on to lollipop and have noticed an issue with photos and videos after they have been taken .

Basically what happens is the phone wont -

Show you the picture from the preview button
Show in the gallery but can be viewed via a file manager
They also do not get backed up to one drive or Google drive

Anything I can do short of re flashing the rom ?
