Broken permalinks in IIS – how to fix?

Hi there,

I’ve got something really wierd happening in my media library.

I’m using a child theme for business-feature. On a windows server IIS7.

When I upload a picture into the media library – it uploads OK, and produces a URL for the image.

Once its uploaded though, I can’t see the image thumbnail in the media list, and when I put the image into a post it doesn’t show.

Very Wierdly though I can click into the image to edit it and I can see it.

Has anyone any ideas? I’ve uploaded some screen grabs that I thought might help.
