InDesign CS6 Margins and Columns don't show up

[Guest]

Hi everyone.

Since yesterday I have a problem in InDesign CS6.
I created margins and columns on my Master Pages, but they don't show in the documents pages...
My guides are activated, also my Baseline Grid and I can see them. (I now created guides, so I can work somehow, but I want to know what's the problem).
Is it a bug?
Can anyone help?

Thanks!

Here two pictures to clarify the situation:

You pressed a quick key and turned off guides. Just go to view-grids & guides-show guides

I solved this by placing a random guide with the ruler, then boom, the margins magically appeared
