As most administrators of the Citrix NetScaler VPX 1000 appliance know, while the location of configuration settings remain the same, the look and feel of the management interface has gone through a change from version 9.3 to 10. I haven’t had any issues with the management interface in the past with version 9.3 but experienced a frustrating issue with version 10 today where I could not load the administration web interface once I’ve logged in. The following is the appliance information I was using:
Version
- NS10.0
- Build 71.6.nc
- Date: Oct 14 2012
- 06:39:56
What basically happens that I will navigate to the management web interface and get presented with the login page:
Logging in works fine but once authenticated, I get presented with the following blank page:
Notice the little exclamation mark at the bottom left hand corner. Clicking on it brings up the following window:
Errors on this webpage might cause it to work incorrectly

I’ve tried this on the following Java and IE versions:
IE: 8.0.7600.16385
Java:
- Version 7 Update 9 (build 1.7.0_09-b05)
- Version 6 Update 32 (build 1.6.0_23-b05)
What’s strange is that if I were to change the URL in the browser from:
http://someIPaddress/menu/neo
… to…
http://someIPaddress/menu/guia
… which is the URL used in the version 9.3 or earlier NetScaler, I would be able to get the administration page to display in the older version 9.3 look and feel:
The only way I was able to fix this was to upgrade Internet Explorer from version 8 to version 9 and use Java 7.
When I use Internet Explorer version 9 with Java 6 Update 32, I receive the following error:
We were unable to return you to the page you were viewing.
Internet Explorer has stopped trying to restore this ewbsite. It appears that the ewbsite continues to have a problem.
