Here's a similar post containing a screen grab from FireBug:
The html pages are fine. Even the WordPress wp-admin back end thing loads fine but without the CSS.
I have access to the server. It's a Windows server running IIS7. This is an issue that's just started, it wasn't like this on friday night and nothing was changed by me (or anyone else in the company as far as I know).
As you see I'm getting the error: "The page cannot be displayed because an internal server error has occurred."
I am really stuck on fixing this, can anyone help out?
