Looks like there is another vulnerability discovered in WordPress, that’s why I have to upload all 3.1MB of files again to all the accounts I have WP installed. After backing up the account and downloading backup.
Maybe I am being too quirky, but I would just post files that need to be updated – just like other PHP projects do – Joomla, Invision Power Board and so on.
On the other hand – maybe (just maybe) it’s time to move to SVN way of managing the multiple installations…
