I have a WordPress 3.0.4 installation that won't show it admin pages on 1 pc. Sadly this is my main pc and the one is usually use to update the site.
I was used to be able to update on this pc as well, although it presented me with a blank screen after posts updates etc. I could live with this problem, since it still updated the posts and added new posts.
Since about a week I only see a blank screen when going to the admin pages. The admin pages itself work perfectly. I've tested them on 3 other computer without any problem.
On the pc where it won't work it doesn't matter what browser I use: Chrome, Firefox, IE8. None of them work.
I've cleared the cookies, and still nothing.
It's not the workpress installation or any plugins since it works on other pc's.
The pc where it doesn't work is a developers computer (Windows 7), it has IIS, Visual Studio, etc.
I've tried other developers pc and they work fine.
