I am receiving this whilst logged in as host or admin and trying to access 'Admin' - 'Site Settings'.
The real portal domain has been replaced by '###' by myself for this post.
I have restarted my machine as well as the application on the remote web host already but no results...
This was all working fine until recently when I installed a new language pack. Now I cannot get into the 'Admin' - 'Site settings' to change the default language. I have already modified my web.config to reflect the new language.

I would appreciate any feedback from anyone who has encountered a similar problem or has a resolution to this problem.

Thanks,
Deon
