Permalinks are working well…except one minor problem. PHP files that I have in the root folder of my site now show ‘page cannot be displayed’ (or perhaps just individual php files that are created outside of wordpress’s posts and pages). http://www.shadowvillepro.com/subscribe.php used to work fine prior to permalinks…now http://www.shadowvillepro.com/subscribe.php just has Page Cannot Be Displayed.

Please note this problem lies within only IE, not Firefox. What could be the explanation for this?
