Can't see that's it any of them.
I pressed the "update files" button in the admin; I even ftp'd them up afterwards to make sure.
I exited the browser and restarted it. I tried in Opera and in IE.
I have a normal Internet connection, Tiscali and am with Yahoo SmallBusinesses which includes WordPress.
There are no plug-ins active or even listed than I can see - there is one called the WordPress database backup - but that is not even active.
To be honest I have had nothing but problems with WordPress, despite the (usually) nice interface there is a lack of contextual explanations as if it is assumed you know about it all already. The number of questions being posted on these forums would perhaps lessen if things were explained better, but then anyone who has ever read a computer manual will know that techies are not the best at that sort of thing ;)
