I've got a very strange behaviour with my wordpress site.
Two articles called with IE returns 404 Not Found.
The same articles called with FF are ok.
This happens also if the permalink are not used and calling with the ?p= parameter, and also if permalink are not activated
Works with FF, doesn't show with IE
Works with both browsers
The articles are using exactly the same template (so i would exclude problems in CSS like missing files).
The very weird fact is that all the new articles i insert seem suffer the same problem but old articles still working ok...
