Internet Explorer 9 not working with PANOS 5.0

Not applicable


We're experiencing an issue with Internet Explorer 9 after upgrading to PANos 5.0

After we login into the firewall we don't get to see anything. The screen remains white after the login.

We have also tested it with Firefox 16 and Chrome but we don't have any issues with those browsers.

Resetting, uninstalling and reinstalling IE9 does not seem to help.

Does anyone know what's happening?

disable the compatibility mode in Internet Explorer, then it works.

What about the debug page?

I think its "hidden" at https://<ip of PA device>/debug

Your role must be superuser (I think) otherwise you will just get an error text in return.

Thanks for the suggestion, I think I am one step closer.

The /debug doesn't seem to help at first. But when I try to log in by IP-adres rather then the DNS name it does seem to work.

I don't seem to get any additional information though.

We used to be able to login with the DNS name before. So I don't understand what's wrong now.

Any news here?
Have the same problem with Panorama (upgrade from 4.1.7 to 5.0)

You're sure? Dosn't work in my case.

Yes, it is reproducable. When you have the blank page after login, press F12 to open Developer Tools in IE9. Then change (click on the text to get a drop down menu) Browsermodus to IE9 and Dokumentmodus to IE9 Standard (Seitenstandard).

Ah OK, that works

I found IE8's default settings didn't work with PANOS 5.0.2, but did work with PANOS 5.0.4

I also found a Knowledge base article about enabling compatibility mode: (created a month after your problem).

also has some suggestions.
