I'd think you'll need to give a bit more information. ;) Which release of FreeNAS? Which nbrowser are you using? On which operating system are you using this browser? Have you checked with another browser? Have you disabled any plugins to see if that's the cause of your problem? Is it only the Network Global config that's 'missing'? When you say you 'can't see' that page, what exactly do you mean (what are the steps to reproduce this) and what do you see?
It was not real cause of NETWORK information page error.
Yesterday I saw that.
When I call web pages in IE8 on WinXP, I could not see that.
But,, at the same time, I could see that in IE9 on Win7 computer!!!
