I upgraded to 2.5.1 and now my posts and pages (http://www.tobeanentrepreneur.com/blog/about-the-author) show a 404/Whoops! That Page Isn't Here error ONLY in firefox/safari but work fine in ie.
The front page is fine, it's only when you click down to an individual post or page (permalinks) that it shows this error?
I have tried everything, the database is fine, the pretty links are fine (have tried every combo), the template also works fine on another blog, .htaccess is working ok etc
Anyone know why it would work ok in one browser and not next?
