So let’s say you are using IE9 and you go to the Site Navigation Settings page on a 2007 SharePoint site and see this:
And you scratch you head and wonder, “Where are all my navigation settings?” Perhaps you did this many moons ago and you think it’s just old age setting in. But a little Googling indicates you aren’t going crazy (or senile) and there’s some JavaScript issue with the page.
Try this. Start IE9 without any add-ons by executing
iexplore –extoff
Then, navigate to the same page and voilà, your navigation editing area appears!
This must be due to some malcontent add-on.
Enabling and disabling add-ons and refreshing your page brings you to NameCtrl Class being the add-on that seems to be causing the problem. Disabling this add-on fixes the issue…at least it did for me!
