Administration console appears as a blank page
We've just installed the 64bit Zimbra 6.07 virtual appliance, run the configuration but when trying to access the admin console (https://192.168.1.3:7071/zimbraAdmin) it first brings up the loading configuration page then redirects to a blank page.
The zimbra appliance was downloaded from: http://files.zimbra.com/zca/zca-6.0....ra_607_341.zip then converted to ovf format using ovftool.
The strange thing is that if I login into the webmail client using the admin account then click the domain admin link in the top right hand corner, it actually brings up a cut down version of the configuration page but only has dashboard, settings and advanced tools tabs at the top of the page. It's missing the left navigation to set the server settings etc.
I've tried re-installing the virtual appliance however I get the same problem.
