[wp-testers] PHP Errors

[Lorenzo]

I've make a (clear) installation of WP 2.3 B3, I've received my password for
the "admin" user, I tried to login but I received these errors:

*Warning*: fwrite(): supplied argument is not a valid stream resource in *
wp-includes/update.php* on line *34*
*Warning*: feof(): supplied argument is not a valid stream resource in *
/wp-includes/update.php* on line *35*
*Warning*: fgets(): supplied argument is not a valid stream resource in */
wp-includes/update.php* on line *36*

All the page is full of those errors...
