I have recently started using wordpress so am not 100% familiar with it. Anyway last week I updated word press to version 2.3.
The CSS on the admin panel at that point seemed fine but today after visiting it for the first time in a while I notice the CSS is not working in Firefox (but it is in internet explorer).
The address for the CSS is http://blog.petermcdonald.co.uk/wp-admin/wp-admin.css?version=2.3 (notice the version variable)
If I enter that address into Firefox I get a 404 not found error. If I take the version variable off it loads fine.
I have not edited any pages at all. What could be causing this problem?
