SG300 Upgrade/Backup page not loading

[ddexter666]

Just purchased a SG300-52 and am trying to upgrade the firmware to 1.1.2 but cannot get the Upgrade/Backup Firmware Language page to load in the web browser interface.  I have tried IE 8 and 9, Firefox 3.16 and 10.02, and Chrome from Windows 7 and XP Pro systems also tried FF and Chrome from Ubuntu system. 

The page just never loads - doesn't show anything.

The same is true of the Download/Backup/Configuration/Log page.  The other links under Administration > File Management seem to work fine.

Any suggestions will be greatly appreciated,

Thank you.

Hi David,

Can you ensure that you DISABLE pop-up blockers on you browser.

Also enclosing an admin guide book link
