Can't view navigation tree

[aileenPPH]

I suddenly lost the navigation tree from my Marketo. Please advise how I can switch it on again.

That's... pretty weird!

Can you post a screenshot of exactly what you're seeing?

In all browsers?

Hello @aileenPPH ,

There is a rare bug that makes it disappear. 

If you clear cookies, cache, etc, try different browsers, log out, log in, etc (all suggestions Marketo support will ask you to do first), you can open a support ticket, and they can clear the palette and/or clear tree cache for you.  They should know why to try first.

Thank you
