Indesign can't select any object or layer

[lewiscaswell]

I've opened an Indesign file which I last worked on a month or so ago.

The artboard looks normal - however I can't select anything.

All of my separate layers are showing in the layers panel, however within them, there is nothing showing at all. E.g I have layers for guides, artwork etc. but they are all showing as empty.

However, when I HIDE each layer, they correctly disappear on the artboard.

So it's like a completely flat document but with nothing selectable whatsoever. Layers intact but no objects showing within them.

Either everything is locked - or everything is on a MasterSpread. 

Can you Ctrl+Click on an object? If it's on a Master it should get overriden on the active page. 

Or switch Preview mode and look for padlocks in the top-left corner.

Lifesaver - it's a document which I was supplied so I didn't realise there was 'master' pages. Thanks so much for your help really appreciate it.
