[development] Drupal 4.7b4 problem with passwords

I don't know if I should ask this here or on support but as it is about 4.7 beta 4 I decided to start here. I upgraded from b3 to b4 and I cannot log in, neither can I set a password, when I try to set a password I get this: * warning: array_merge() [function.array-merge.html]: Argument #2 is not an array in /var/www/fbdrupal/includes/form.inc on line 180. * warning: Missing argument 1 for password_confirm_validate() in /var/www/fbdrupal/includes/form.inc on line 595. Is this a problem with b4 or have I messed up somewhere? -- Martin Tomes echo 'martin at tomes x org x uk'\ | sed -e 's/ x /\./g' -e 's/ at /@/' The Subversion Wiki is at http://www.subversionary.org/
