I was working on our dotNetNuke site with a Navigation bar and added it to all pages. I then edited the Navigation bar, pulled off the Display on All Pages check box in the Settings dialog box, and then rechecked it. It would not display on all pages after this. This is apparently a bug in the DNN system and this is the workaround.
Go to Admin – Recycle Bin and Click “Empty Recycle Bin” button.
Then go back to the Module – Settings and recheck “Display on All Pages”. It should work.
I found help here.
